“Whether you are a parent or not, carving out time to turn off your devices, to disconnect from the wired world and engage with the real people who are all around you, is one of the best gifts you can give yourself and the people you love.”
Back in 2015, Habyts hosted a number of globally respected experts in Parenting, Learning and Online Gaming as part of our Screen Time Sanity Telesummit 2015.
Our experts shared their knowledge and experience across a number of key topics including setting screen time limits, teaching emotional intelligence and experimenting with a 30-day screen detox.
“Whether you are a parent or not, carving out time to turn off your devices, to disconnect from the wired world and engage with the real people who are all around you, is one of the best gifts you can give yourself and the people you love.”
“We may have to exercise discipline to use the controls we have but we are not slaves to these devices unless we allow ourselves to become so. To me, the trick is to put yourself in charge of your screens instead of allowing your screens to be in charge of you.”
“The key is to teach them how to be safe with technology, because ultimately, we want our children to be in charge of technology, rather than feeling technology is in charge of them.”
“Part of what happens is instead of looking at technology as a tool and a valuable thing, it ends up being a toy that our kids have permission or not to use and that ends up putting us in the position of being the bad guy.”
“Taking a month to cleanse yourself from screens as much as you physically and possibly can, not shooting for perfection but just shooting for connection. You might learn something that you didn’t realize about the people who are closest to you.”
A recent study by the University of Washington and University of Michigan found children have clear screen time expectations of their parents too, namely:Autonomy – Allow your kids to make their own decisions about technology use.

In an office, it"s common to see people using multiple monitors at the same computer. It"s a great way to expand your workspace and use lots of different apps at once.
Luckily, dual monitors aren"t just for professionals. You can set up dual monitors on your PC and Mac easily. You just need the monitors and cables to connect them.Important: You can set up dual monitors on a laptop, too. The laptop"s screen will just count as one of the monitors.
1.Connect both monitors to the computer tower or laptop you"re using, and make sure they"re both turned on. Depending on the monitor and your computer, you"ll need a VGA, HDMI, or USB cable. In some cases, you might need a combination of different cables.
3.Scroll down to the Multiple Displays option, open the drop-down menu, and choose how you want the dual monitors to work. Here are your options:Extend these displays:You can set your screens up so that they display different things and your mouse cursor can move between them.
3.Two windows will open, one on each display. The window on your main display will have more options — use this window and click Arrangement at the top.

Screen-Free Week happens each year now. But I don’t want you to feel shamed if you haven’t been participating or participating as fully as you’d like. Many of us work online or have school assignments online that prevent us from participating fully. And others just don’t feel ready to give up screen time.
This post isn’t about shaming. It simply acknowledges that most of us would like to have less screen time. It’s about giving us inspiration to find the right balance in our life and family.
“I introduced the term nature-deficit disorder—not as a medical diagnosis but as a way to describe the growing gap between children and nature. By its broadest interpretation, nature-deficit disorder is an atrophied awareness, a diminished ability to find meaning in the life that surrounds us. When we think of the nature deficit, we usually think of kids spending too much time indoors plugged into an outlet or computer screen. But after the book’s publication, I heard adults speak with heartfelt emotion, even anger, about their own sense of loss.” Richard Louv
“Unlike television, nature does not steal time; it amplifies it. Nature offers healing for a child living in a destructive family or neighborhood.” Richard Louv, Last Child in the Woods: Saving Our Children from Nature-Deficit Disorder
“What would our lives be like if our days and nights were as immersed in nature as they are in technology?” Richard Louv, The Nature Principle: Human Restoration and the End of Nature-Deficit Disorder
“Sometimes you have to disconnect to stay connected. Remember the old days when you had eye contact during a conversation? When everyone wasn’t looking down at a device in their hands? We’ve become so focused on that tiny screen that we forget the big picture, the people right in front of us.” Regina Brett
“I have come to the feeling about television the way I do about hamburgers: I eat a lot of hamburgers and I don’t remember a single one of them.” John Barrow, 1973
“If you came and you found a strange man… teaching your kids to punch each other, or trying to sell them all kinds of products, you’d kick him right out of the house, but here you are; you come in and the TV is on, and you don’t think twice about it.” Jerome Singer

“I"ve been in auditions without screens, and I can assure you that I was prejudiced. I began to listen with my eyes, and there is no way that your eyes don"t affect your judgement. The only true way to listen is with your ears and your heart. (p.251)”
“The pace of this modern age is not conducive to maintaining one’s consciousness. Glued to our electronics, we are blind and deaf to the world around us. Run down by our long work days, we are too exhausted to think and too hurried to feel. The day ends in a haze of strained thoughts, numbness, and fatigue. And we rise the next morning only to start the cycle again.
In this age of distraction, if you desire to fritter away your life with empty diversions, there is an abundance of gadgets available to aid you. Quietness is a characteristic of ages gone by. Our generation is the one it died with. Connected to the virtual world, we ignore the presence of those in our home. One can only hope we will awaken to the need for balance before we look up from the screen to find our loved ones have gone, and our life has passed us by.”
“People are obsessed with spectacle. We live in the society of the spectacle. People are addicted to the spectacular. They want bigger and better spectacles. They need more and more to keep them stimulated. They crave entertainment. They crave more powerful simulations, more breathtaking special effects, more everything. No one wants POR – plain old reality. Simulation – hyperreality – the simulacrum – these are what the people desire. We all live in Disneyland now – an utter fantasy world. Our true God is Mickey Mouse. At least he’s a lot nicer than Yahweh.”
“The simulated perfection that surrounds us is mediated by screens. On every screen we look at it, perfection stares out at us. Screens are everywhere. We are always staring at screens. Cinema screens, TV screens, iPhone screens, computer screens… Screens are omnipresent in our lives. And they are the delivery mechanisms of perfect images of perfect lives. Celebrities, the nobility and the super rich are those with the perfect lives we so envy. They rule the screens.”
That world can no longer either be reflected or represented; it can only be refracted or diffracted now by operations that are, without distinction, operations of brain and screen - the mental operations of a brain that has itself become a screen.
The other side of this Integral Reality is that everything operates in an integrated circuit. In the information media - and in our heads too - the image-feedback dominates, the insistent presence of the monitors - this convolution of things that operate in a loop, that connect back round to themselves like a Klein bottle, that fold back into themselves. Perfect reality, in the sense that everything is verified by adherence to, by confusion with, its own image.
This process assumes its full magnitude in the visual and media world, but also in everyday, individual life, in our acts and thoughts. Such an automatic refraction affects even our perception of the world, sealing everything, as it were, by a focusing on itself.
It is a phenomenon that is particularly marked in the photographic world, where everything is immediately decked out with a context, a culture, a meaning, an idea, disarming any vision and creating a form of blindness condemned by Rafael Sanchez Ferlosio: "There exists a terrible form of blindness which very few people notice: the blindness that allows you to look and see, but not to see at a stroke without looking. That is how things were before: you didn"t look at them, you were happy simply to see them. Everything today is poisoned with
duplicity; there is no pure, direct impulse. So, for example, the countryside has become "landscape" or, in other words, a representation of itself ...”
“.. almost every face and every voice and scrap of language in this world rises up through a screen or wire like something coming to the surface from the bottom of a lake, or on the other side of some mirrored glass where you can’t quite touch it.”
“The ends of the screen continued to exceed the fields of meaning and create others that immediately, and almost through the impetus of their unfolding, cut huge and savage zigzags. Astronomy. The ability of parrots and blackbirds to speak. The diesel engine. The Assyrians. Coffee. Clouds. Screens, screens, and more screens. They were proliferating everywhere, and he had to pay close attention to make sure that no sector failed to be sorted. Fortunately, Dr. Aira had no time to notice the stress he was experiencing. Attention was key, and perhaps no man had ever brought as much of it to bear as he did for that hour. If the circumstances had been less serious, if he had been able to adopt a more frivolous perspective, he could have said that the entire procedure was an incomparable creator of attention, the most exhaustive ever conceived to exercise this noble mental faculty. And it did not require an extraordinary person; a common man could do it (and Dr. Aira would have been quite satisfied to become a common man), for the Cure created all the attention it demanded. It wasn’t like those video games, which are always trying to trick it or avoid it or get one step ahead of it; to continue with this simile, it should be said that the operator of the Cure was his own video game, his own screen, and his own decoys, and that far from defying attention, they nurtured it. Despite all this, the effort was superhuman, and it was yet to be seen if Dr. Aira could hold out till the end.”
“If anything, screens make me feel life too much. Screens bring hilarious highs and crushing lows... What I"m really missing is just the feeling of neutral. Maybe that"s the real value of logging off and going outside—to help us remember what neutral feels like.”
Tip:If you"re using a wireless display adapter, connect to an HDMI port on newer TVs, then wirelessly connect your PC to it. After connecting your wireless display adapter to your TV, go to your Windows 11 PC, press Windows logo key + K to open Cast, then select your wireless display adapter.
To see which number corresponds to a display, select Start, then search for settings. Select Settings > System > Display> Identify. A number appears on the screen of the display it"s assigned to.
If you have multiple displays, you can change how they"re arranged. This is helpful if you want your displays to match how they"re set up in your home or office. In Display settings, select and drag the display to where you want. Do this with all the displays you want to move. When you"re happy with the layout, select Apply. Test your new layout by moving your mouse pointer across the different displays to make sure it works like you expect.
After you"re connected to your external displays, you can change settings like your resolution, screen layout, and more. To see available options, in Settings, select System > Display.
Windows will recommend an orientation for your screen. To change it in Display settings, under Scale & layout, choose your preferred Display orientation. If you change the orientation of a monitor, you"ll also need to physically rotate the screen. For example, you"d rotate your external display to use it in portrait instead of landscape.

A computer monitor is an output device that displays information in pictorial or textual form. A discrete monitor comprises a visual display, support electronics, power supply, housing, electrical connectors, and external user controls.
The display in modern monitors is typically an LCD with LED backlight, having by the 2010s replaced CCFL backlit LCDs. Before the mid-2000s,CRT. Monitors are connected to the computer via DisplayPort, HDMI, USB-C, DVI, VGA, or other proprietary connectors and signals.
Originally, computer monitors were used for data processing while television sets were used for video. From the 1980s onward, computers (and their monitors) have been used for both data processing and video, while televisions have implemented some computer functionality. In the 2000s, the typical display aspect ratio of both televisions and computer monitors has changed from 4:3 to 16:9.
Early electronic computer front panels were fitted with an array of light bulbs where the state of each particular bulb would indicate the on/off state of a particular register bit inside the computer. This allowed the engineers operating the computer to monitor the internal state of the machine, so this panel of lights came to be known as the "monitor". As early monitors were only capable of displaying a very limited amount of information and were very transient, they were rarely considered for program output. Instead, a line printer was the primary output device, while the monitor was limited to keeping track of the program"s operation.
The first computer monitors used cathode-ray tubes (CRTs). Prior to the advent of home computers in the late 1970s, it was common for a video display terminal (VDT) using a CRT to be physically integrated with a keyboard and other components of the workstation in a single large chassis, typically limiting them to emulation of a paper teletypewriter, thus the early epithet of "glass TTY". The display was monochromatic and far less sharp and detailed than on a modern monitor, necessitating the use of relatively large text and severely limiting the amount of information that could be displayed at one time. High-resolution CRT displays were developed for specialized military, industrial and scientific applications but they were far too costly for general use; wider commercial use became possible after the release of a slow, but affordable Tektronix 4010 terminal in 1972.
Some of the earliest home computers (such as the TRS-80 and Commodore PET) were limited to monochrome CRT displays, but color display capability was already a possible feature for a few MOS 6500 series-based machines (such as introduced in 1977 Apple II computer or Atari 2600 console), and the color output was a speciality of the more graphically sophisticated Atari 800 computer, introduced in 1979. Either computer could be connected to the antenna terminals of an ordinary color TV set or used with a purpose-made CRT color monitor for optimum resolution and color quality. Lagging several years behind, in 1981 IBM introduced the Color Graphics Adapter, which could display four colors with a resolution of 320 × 200 pixels, or it could produce 640 × 200 pixels with two colors. In 1984 IBM introduced the Enhanced Graphics Adapter which was capable of producing 16 colors and had a resolution of 640 × 350.
By the end of the 1980s color progressive scan CRT monitors were widely available and increasingly affordable, while the sharpest prosumer monitors could clearly display high-definition video, against the backdrop of efforts at HDTV standardization from the 1970s to the 1980s failing continuously, leaving consumer SDTVs to stagnate increasingly far behind the capabilities of computer CRT monitors well into the 2000s. During the following decade, maximum display resolutions gradually increased and prices continued to fall as CRT technology remained dominant in the PC monitor market into the new millennium, partly because it remained cheaper to produce.
There are multiple technologies that have been used to implement liquid-crystal displays (LCD). Throughout the 1990s, the primary use of LCD technology as computer monitors was in laptops where the lower power consumption, lighter weight, and smaller physical size of LCDs justified the higher price versus a CRT. Commonly, the same laptop would be offered with an assortment of display options at increasing price points: (active or passive) monochrome, passive color, or active matrix color (TFT). As volume and manufacturing capability have improved, the monochrome and passive color technologies were dropped from most product lines.
The first standalone LCDs appeared in the mid-1990s selling for high prices. As prices declined they became more popular, and by 1997 were competing with CRT monitors. Among the first desktop LCD computer monitors was the Eizo FlexScan L66 in the mid-1990s, the SGI 1600SW, Apple Studio Display and the ViewSonic VP140vision science remain dependent on CRTs, the best LCD monitors having achieved moderate temporal accuracy, and so can be used only if their poor spatial accuracy is unimportant.
High dynamic range (HDR)television series, motion pictures and video games transitioning to widescreen, which makes squarer monitors unsuited to display them correctly.
Organic light-emitting diode (OLED) monitors provide most of the benefits of both LCD and CRT monitors with few of their drawbacks, though much like plasma panels or very early CRTs they suffer from burn-in, and remain very expensive.
Radius of curvature (for curved monitors) - is the radius that a circle would have if it had the same curvature as the display. This value is typically given in millimeters, but expressed with the letter "R" instead of a unit (for example, a display with "3800R curvature" has a 3800mm radius of curvature.
Display resolution is the number of distinct pixels in each dimension that can be displayed natively. For a given display size, maximum resolution is limited by dot pitch or DPI.
Dot pitch represents the distance between the primary elements of the display, typically averaged across it in nonuniform displays. A related unit is pixel pitch, In LCDs, pixel pitch is the distance between the center of two adjacent pixels. In CRTs, pixel pitch is defined as the distance between subpixels of the same color. Dot pitch is the reciprocal of pixel density.
Pixel density is a measure of how densely packed the pixels on a display are. In LCDs, pixel density is the number of pixels in one linear unit along the display, typically measured in pixels per inch (px/in or ppi).
Contrast ratio is the ratio of the luminosity of the brightest color (white) to that of the darkest color (black) that the monitor is capable of producing simultaneously. For example, a ratio of 20,000∶1 means that the brightest shade (white) is 20,000 times brighter than its darkest shade (black). Dynamic contrast ratio is measured with the LCD backlight turned off. ANSI contrast is with both black and white simultaneously adjacent onscreen.
Color depth - measured in bits per primary color or bits for all colors. Those with 10bpc (bits per channel) or more can display more shades of color (approximately 1 billion shades) than traditional 8bpc monitors (approximately 16.8 million shades or colors), and can do so more precisely without having to resort to dithering.
Color accuracy - measured in ΔE (delta-E); the lower the ΔE, the more accurate the color representation. A ΔE of below 1 is imperceptible to the human eye. A ΔE of 2–4 is considered good and requires a sensitive eye to spot the difference.
Refresh rate is (in CRTs) the number of times in a second that the display is illuminated (the number of times a second a raster scan is completed). In LCDs it is the number of times the image can be changed per second, expressed in hertz (Hz). Determines the maximum number of frames per second (FPS) a monitor is capable of showing. Maximum refresh rate is limited by response time.
Response time is the time a pixel in a monitor takes to change between two shades. The particular shades depend on the test procedure, which differs between manufacturers. In general, lower numbers mean faster transitions and therefore fewer visible image artifacts such as ghosting. Grey to grey (GtG), measured in milliseconds (ms).
On two-dimensional display devices such as computer monitors the display size or view able image size is the actual amount of screen space that is available to display a picture, video or working space, without obstruction from the bezel or other aspects of the unit"s design. The main measurements for display devices are: width, height, total area and the diagonal.
The size of a display is usually given by manufacturers diagonally, i.e. as the distance between two opposite screen corners. This method of measurement is inherited from the method used for the first generation of CRT television, when picture tubes with circular faces were in common use. Being circular, it was the external diameter of the glass envelope that described their size. Since these circular tubes were used to display rectangular images, the diagonal measurement of the rectangular image was smaller than the diameter of the tube"s face (due to the thickness of the glass). This method continued even when cathode-ray tubes were manufactured as rounded rectangles; it had the advantage of being a single number specifying the size, and was not confusing when the aspect ratio was universally 4:3.
With the introduction of flat panel technology, the diagonal measurement became the actual diagonal of the visible display. This meant that an eighteen-inch LCD had a larger viewable area than an eighteen-inch cathode-ray tube.
Estimation of monitor size by the distance between opposite corners does not take into account the display aspect ratio, so that for example a 16:9 21-inch (53 cm) widescreen display has less area, than a 21-inch (53 cm) 4:3 screen. The 4:3 screen has dimensions of 16.8 in × 12.6 in (43 cm × 32 cm) and area 211 sq in (1,360 cm2), while the widescreen is 18.3 in × 10.3 in (46 cm × 26 cm), 188 sq in (1,210 cm2).
Until about 2003, most computer monitors had a 4:3 aspect ratio and some had 5:4. Between 2003 and 2006, monitors with 16:9 and mostly 16:10 (8:5) aspect ratios became commonly available, first in laptops and later also in standalone monitors. Reasons for this transition included productive uses for such monitors, i.e. besides Field of view in video games and movie viewing, are the word processor display of two standard letter pages side by side, as well as CAD displays of large-size drawings and application menus at the same time.LCD monitors and the same year 16:10 was the mainstream standard for laptops and notebook computers.
In 2010, the computer industry started to move over from 16:10 to 16:9 because 16:9 was chosen to be the standard high-definition television display size, and because they were cheaper to manufacture.
In 2011, non-widescreen displays with 4:3 aspect ratios were only being manufactured in small quantities. According to Samsung, this was because the "Demand for the old "Square monitors" has decreased rapidly over the last couple of years," and "I predict that by the end of 2011, production on all 4:3 or similar panels will be halted due to a lack of demand."
The resolution for computer monitors has increased over time. From 280 × 192 during the late 1970s, to 1024 × 768 during the late 1990s. Since 2009, the most commonly sold resolution for computer monitors is 1920 × 1080, shared with the 1080p of HDTV.2560 × 1600 at 30 in (76 cm), excluding niche professional monitors. By 2015 most major display manufacturers had released 3840 × 2160 (4K UHD) displays, and the first 7680 × 4320 (8K) monitors had begun shipping.
Every RGB monitor has its own color gamut, bounded in chromaticity by a color triangle. Some of these triangles are smaller than the sRGB triangle, some are larger. Colors are typically encoded by 8 bits per primary color. The RGB value [255, 0, 0] represents red, but slightly different colors in different color spaces such as Adobe RGB and sRGB. Displaying sRGB-encoded data on wide-gamut devices can give an unrealistic result.Exif metadata in the picture. As long as the monitor gamut is wider than the color space gamut, correct display is possible, if the monitor is calibrated. A picture which uses colors that are outside the sRGB color space will display on an sRGB color space monitor with limitations.Color management is needed both in electronic publishing (via the Internet for display in browsers) and in desktop publishing targeted to print.
Most modern monitors will switch to a power-saving mode if no video-input signal is received. This allows modern operating systems to turn off a monitor after a specified period of inactivity. This also extends the monitor"s service life. Some monitors will also switch themselves off after a time period on standby.
Most modern laptops provide a method of screen dimming after periods of inactivity or when the battery is in use. This extends battery life and reduces wear.
Many monitors have other accessories (or connections for them) integrated. This places standard ports within easy reach and eliminates the need for another separate hub, camera, microphone, or set of speakers. These monitors have advanced microprocessors which contain codec information, Windows interface drivers and other small software which help in proper functioning of these functions.
Monitors that feature an aspect ratio greater than 2:1 (for instance, 21:9 or 32:9, as opposed to the more common 16:9, which resolves to 1.77:1).Monitors with an aspect ratio greater than 3:1 are marketed as super ultrawide monitors. These are typically massive curved screens intended to replace a multi-monitor deployment.
These monitors use touching of the screen as an input method. Items can be selected or moved with a finger, and finger gestures may be used to convey commands. The screen will need frequent cleaning due to image degradation from fingerprints.
Some displays, especially newer flat panel monitors, replace the traditional anti-glare matte finish with a glossy one. This increases color saturation and sharpness but reflections from lights and windows are more visible. Anti-reflective coatings are sometimes applied to help reduce reflections, although this only partly mitigates the problem.
Most often using nominally flat-panel display technology such as LCD or OLED, a concave rather than convex curve is imparted, reducing geometric distortion, especially in extremely large and wide seamless desktop monitors intended for close viewing range.
Newer monitors are able to display a different image for each eye, often with the help of special glasses and polarizers, giving the perception of depth. An autostereoscopic screen can generate 3D images without headgear.
A combination of a monitor with a graphics tablet. Such devices are typically unresponsive to touch without the use of one or more special tools" pressure. Newer models however are now able to detect touch from any pressure and often have the ability to detect tool tilt and rotation as well.
The option for using the display as a reference monitor; these calibration features can give an advanced color management control for take a near-perfect image.
A desktop monitor is typically provided with a stand from the manufacturer which lifts the monitor up to a more ergonomic viewing height. The stand may be attached to the monitor using a proprietary method or may use, or be adaptable to, a VESA mount. A VESA standard mount allows the monitor to be used with more after-market stands if the original stand is removed. Stands may be fixed or offer a variety of features such as height adjustment, horizontal swivel, and landscape or portrait screen orientation.
The Flat Display Mounting Interface (FDMI), also known as VESA Mounting Interface Standard (MIS) or colloquially as a VESA mount, is a family of standards defined by the Video Electronics Standards Association for mounting flat panel displays to stands or wall mounts.
A fixed rack mount monitor is mounted directly to the rack with the flat-panel or CRT visible at all times. The height of the unit is measured in rack units (RU) and 8U or 9U are most common to fit 17-inch or 19-inch screens. The front sides of the unit are provided with flanges to mount to the rack, providing appropriately spaced holes or slots for the rack mounting screws. A 19-inch diagonal screen is the largest size that will fit within the rails of a 19-inch rack. Larger flat-panels may be accommodated but are "mount-on-rack" and extend forward of the rack. There are smaller display units, typically used in broadcast environments, which fit multiple smaller screens side by side into one rack mount.
A stowable rack mount monitor is 1U, 2U or 3U high and is mounted on rack slides allowing the display to be folded down and the unit slid into the rack for storage as a drawer. The flat display is visible only when pulled out of the rack and deployed. These units may include only a display or may be equipped with a keyboard creating a KVM (Keyboard Video Monitor). Most common are systems with a single LCD but there are systems providing two or three displays in a single rack mount system.
A panel mount computer monitor is intended for mounting into a flat surface with the front of the display unit protruding just slightly. They may also be mounted to the rear of the panel. A flange is provided around the screen, sides, top and bottom, to allow mounting. This contrasts with a rack mount display where the flanges are only on the sides. The flanges will be provided with holes for thru-bolts or may have studs welded to the rear surface to secure the unit in the hole in the panel. Often a gasket is provided to provide a water-tight seal to the panel and the front of the screen will be sealed to the back of the front panel to prevent water and dirt contamination.
An open frame monitor provides the display and enough supporting structure to hold associated electronics and to minimally support the display. Provision will be made for attaching the unit to some external structure for support and protection. Open frame monitors are intended to be built into some other piece of equipment providing its own case. An arcade video game would be a good example with the display mounted inside the cabinet. There is usually an open frame display inside all end-use displays with the end-use display simply providing an attractive protective enclosure. Some rack mount monitor manufacturers will purchase desktop displays, take them apart, and discard the outer plastic parts, keeping the inner open-frame display for inclusion into their product.
According to an NSA document leaked to Der Spiegel, the NSA sometimes swaps the monitor cables on targeted computers with a bugged monitor cable in order to allow the NSA to remotely see what is being displayed on the targeted computer monitor.
Van Eck phreaking is the process of remotely displaying the contents of a CRT or LCD by detecting its electromagnetic emissions. It is named after Dutch computer researcher Wim van Eck, who in 1985 published the first paper on it, including proof of concept. Phreaking more generally is the process of exploiting telephone networks.

For our first project, we’re using both the inbuilt LCD screen and WiFi module to get text data of famous quotes. Since we’re all nerds at DIYODE, we’ve of course chosen to choose famous programming quotes. The center button of the Wio Terminal will be used to load a new quote and display it on the screen.
WiFi is involved here because we’re using a simple Web API to gather data and display it live. Since it’s connecting to WiFi, we could connect it with virtually any other web interface and make it work.
If you’re new to programming, this code may appear daunting, but it’s really just our Wio Terminal pretending to be a computer sending a web request and reading the response. An API is just an ‘application programming interface’ and is a fancy way of saying it’ll be the source of our data.
There isn’t a ton of libraries we need to import here. We’re using the Arduino JSON, rpcWiFi and HTTPClient libraries to handle the internet connection and data, and the TFT_eSPI library to handle the screen on the Wio Terminal.
The ‘wasPressed’ variable will be used during the main loop to ensure we only display one new quote when the button is pressed, and not to continue looking for quotes when the button is held. This is typically referred to as state detection, and we’ll talk about this shortly.void setup() {
To make the WiFi and networking features work, you’ll need to reflash the WiFi firmware on the Wio Terminal. The official Seeed guide can be found here:https://wiki.seeedstudio.com/Wio-Terminal-Wi-Fi/
Also notice that there is a considerable number of calls to the Serial command, which essentially allows us to debug and inspect the functionality of the Wio Terminal by opening the Serial Monitor (Shortcut – Ctrl+Shift+M).void loop() {
The getQuoteResponse() function is where the request actually happens, which consists of opening our URL (feel free to visit the URL shown, it will show a random programming quote in your browser), and loading it from a JSON format. We won’t go into JSON formats and the specifics of it in this project, but essentially its a field and value-based system where attributes are given names. Our response usually comes in this format:{"id":"5a6ce86f2af929789500e824","author":"Ken Thompson","en":"One of my most productive days was throwing away 1,000 lines of code."}
Finally, we can actually draw the quote text on the Wio Terminal’s screen! This isn’t that tricky, except for that weird for loop with the numbers in it. The purpose of this is to provide some basic text wrapping.
Text wrapping is the process of bringing text fields down to the next line on the screen if it’s too long – which is often the case with quotes. The LCD library does have this function built-in, but it wasn’t cooperating for us, so we wrote it ourselves!
Essentially, we’re taking ‘chunks’ out of the text with the substring function and writing each to one line of the Wio Terminal’s LCD screen. The ‘len’ variable describes the number of characters on each line. If the function is confusing, just change some values and observe the effects!
We’re all done! Now just hit the upload button, ensuring that the Wio Terminal is switched on. After a couple of seconds of letting it connect to our WiFi…
…and boom! It’s all working. Inspiring programming quotes at the press of a button. Obviously, this isn’t the most practical program ever – but it’s a good starting program to experiment with the Wio Terminal and to demonstrate its capabilities with precisely zero external wiring required.
You may be able to connect one or more external displays to your Mac (you may need a video cable or adapter for each display). See the Apple Support article Adapters for the Thunderbolt 4, Thunderbolt 3, or USB-C port.
For each display, securely connect a video cable (and adapter, if necessary) from a video output port on your Mac to the video input port on the display. See About the video ports.
You can connect one or more external displays, depending on your Mac.For Mac computers with the Apple M1 Chip: You can connect a single external display to your Mac. Docks don’t increase the number of displays you can connect. On a Mac mini with M1 chip, you can connect a second display to the HDMI port. See the Apple Support article Mac computers with Apple silicon.
For Mac computers with Thunderbolt 3 (USB-C): You can connect a single display to each port. If you connect multiple Thunderbolt devices to each other, the Thunderbolt 3 display must be the last device in the chain. If your Thunderbolt 3 display has USB ports, those can be used for data and power.
For Mac computers with Mini DisplayPort, Thunderbolt, or Thunderbolt 2: You can connect up to two displays. If the displays themselves have Thunderbolt ports, you can connect one display to another, and then connect one of the displays to a Thunderbolt port on your Mac. If your Mac has two Thunderbolt ports, you can connect each display to separate Thunderbolt ports on your Mac. A DisplayPort device must be the last device in a chain of connected Thunderbolt devices. See Connect a display, TV, or projector to Mac.
For Mac computers with Thunderbolt 4 (USB-C) and HDMI ports: You can connect up to four external displays to your Mac, depending on your Mac model. See the Apple Support article Connect a display to your Mac.
Note:Only the device directly connected to your Mac receives power from the computer’s Thunderbolt port. The other devices in the chain must be powered by separate power adapters.
You can arrange your displays in any configuration to create an extended desktop. For example, you can set your external display side by side with your Mac to create one large continuous desktop.
If more than two displays are connected to your Mac, you can specify that some displays use mirroring (showing the entire desktop) and other displays show the extended desktop (displaying the desktop across two or more displays). For example, if you have three displays, you can have two displays showing the same information and the third display showing the extended desktop.Press and hold the Option key and drag one display icon onto another display icon to mirror those two displays.

A stock quote is the price of a stock as quoted on an exchange. A basic quote for a specific stock provides information, such as its bid and ask price, last traded price, and volume traded.
All stocks in the U.S. have been quoted in decimals, rather than fractions, since April 9, 2001. As a result, bid-ask spreads have contracted dramatically, with spreads for the most widely traded stocks now as small as a penny, compared with 1/16th of a dollar (or $0.0625) earlier. Decimal pricing has resulted in substantial savings on transaction costs to U.S. investors because of tighter bid-ask spreads.
Investors increasingly access stock quotes online or on mobile devices, such as smartphones, rather than through print media, such as newspapers and magazines. A large number of Internet portals and websites offer delayed stock quotes at no charge, with real-time stock quotes generally restricted to paying subscribers.
Stock quotes can be presented with supplemental information and data, such as the high and low prices for given security that have been recorded over the course of the trading day. It may also show the change in the value of the security compared against the prior day’s closing price or the opening price of the current trading day. This difference in price might be shown as a percentage, revealing how much security has increased or declined in value. Analyst recommendations for a given security might also be presented with a stock quote. Such recommendations could be shown for hourly, daily, weekly, and monthly intervals.
Consider the stock quote for the social media behemoth Meta (formerly Facebook). It is displayed along with supplemental information: the company"s ticker symbol (META), change in price (expressed in terms of percentage), and last quoted price at closing time.
Depending on the service and platform providing stock quotes, the information might strictly revolve around the current, latest pricing, or there can be expanded details such as metrics on the daily, weekly, monthly, and annual performance of the security. A stock quote can also include performance metrics on share prices for a multi-year period.
The pricing displayed with a stock quote reflects the buying and selling activity that influences the value of a given security. As each trading day unfolds, news and industry trends related to a security can affect the way investors choose to handle the shares. When beneficial updates are revealed, such as strong revenue and earnings reported by the company or positive test results for a product, the value of the shares can increase as more investors buy into the company. These shifts are reflected in the stock quotes that shareholders and other watchers of the company will use to make investment decisions.
