arduino tft display clock manufacturer

In electronics world today, Arduino is an open-source hardware and software company, project and user community that designs and manufactures single-board microcontrollers and microcontroller kits for building digital devices. Arduino board designs use a variety of microprocessors and controllers. The boards are equipped with sets of digital and analog input/output (I/O) pins that may be interfaced to various expansion boards (‘shields’) or breadboards (for prototyping) and other circuits.

The boards feature serial communications interfaces, including Universal Serial Bus (USB) on some models, which are also used for loading programs. The microcontrollers can be programmed using the C and C++ programming languages, using a standard API which is also known as the “Arduino language”. In addition to using traditional compiler toolchains, the Arduino project provides an integrated development environment (IDE) and a command line tool developed in Go. It aims to provide a low-cost and easy way for hobbyist and professionals to create devices that interact with their environment using sensors and actuators. Common examples of such devices intended for beginner hobbyists include simple robots, thermostats and motion detectors.

In order to follow the market tread, Orient Display engineers have developed several Arduino TFT LCD displays and Arduino OLED displays which are favored by hobbyists and professionals.

Although Orient Display provides many standard small size OLED, TN and IPS Arduino TFT displays, custom made solutions are provided with larger size displays or even with capacitive touch panel.

Nothing can be compared when you can put your hard work to display on a 4” TFT display- From one end to the other end it"s 480*360 pixel to play with. 4” TFT Analog-GPS clock on Arduino

Every electronic hobbyist dreams to display his work on display – be it LCD, GLCD (64*128), OLED or TFT . LCDs are the oldest type of displays. If putting your work on LCD or GLCD is great then putting it on OLED is certainly greater but nothing can be compared when you can put your hard work to display on a 4” TFT display. From one end to the other end it"s 480*360 pixel to put up with and it"s very very impressive.

The latest Chinese TFT displays are very cheap and works perfectly with Arduino & Raspberry Pi. The TFT ILI9488 display costs about $8 on aliexpress.com. There are two varieties available one with 26 pins 13*2 DIL and the other is with pins aligned exactly to sit on an UNO board.

Arduino style – Directly sits exactly on an Arduino UNO board. The major disadvantage is that once it sits on an UNO board one can hardly use any other GPIO pins for other usages. Both these styles I"ve used for creating art works on Arduino & Raspberry Pi. The Arduino type has an extra SDCard attached and gets connected to the SPI (D-10,11,12,13) pins when inserted.

Hurdles:The main hurdles that I faced with these type of displays is that they are not common and all are made by mcufrends.com. Fortunately the mcufriends.com itself has made and freely distributed the MCUFRIEND_kbd.h header files which works out of the box for these displays and many other type of similar displays. The other header file that are required for this displays are Adafruit_GFX.h [both these header files are added in the archieve]

While the pin connections of the Arduino type is pretty clear and straight forward the same on Raspberry Pi type is not clear at all. However, here"s my hard work for you to make your life easy ! [See the connection diagram for both the types]

While the Arduino type shield is fairly easy to connect but difficult to attach other devices , the Raspberry Pi type shield is little difficult to find out the pin details but it has extremely easy & compact interface while fitted up . Here"s the 26 pin DIL pin details which will go to the same pins of Arduino.

These shields are basically for 3.3 volt operations. But upto 5 volt it works , However, prolong operation on 5 volt is not recommended as it gets heated up profusely. In case you want to free some other Arduino pins then you look into the mcufriend_shield.h file and re-write the connections as I shifted some connections to alternate pins.

Construction:The possibilities are limitless when you can tie up the display so easily. Here"s a GPS ana-digital clock with temperature indicator built with the following Bill Of Materials.

The connections are easy as shown in the schematic diagrams. Since all the top portion of the UNO is covered by the TFT shield, the connections for the LM-35, GPS receiver is taken from the bottom side of the UNO shield.

Software: This is real fun ! With small strokes of code the TFT behaves differently and opens up many different ways of displaying the output. Creating a thick line, making the hands move smoothly was real challenge as the Adafruit_GFX is not so much developed but a look back to the high school trigonometry is all that you need to make it all happen for you.

Operation:The present GPS receivers which have a built in patch antenna on top ,can locate the LEO GPS satellite very easily if you have your windows are open or glass covered. The moment it locates 2 such satellites ,the time starts ticking on the analog dial. At the same time the time is shown digitally on the right side with the temperature display at the bottom. For temperature sensor I"ve used a TMP36 sensor which works on 3.3 volt. However, an LM35 can also be used but you have to have 5volt supply for that.

Time is a critical element of our existence that will never get old, and with technology, we can find better and more intuitive ways to measure it. In one of our past tutorials, we looked at how the DS3231 real time clock module can be used with Arduino to display time on a 16×2 LCD display. Today, we will build an upgrade to that project using an Arduino Due, the DS3231 RTC module and a 3.2″colour TFT display in place of the 16×2 LCD display used in the previous project.

At the heart of today’s project is the DS3231 real time clock module which we will use to obtain the current time, date and temperature of the environment. The DS3231 real time clock module is one of the most popular real-time clock chips among makers and DIY enthusiasts. It is a low-cost, highly accurate, I2Cbased real-time clock (RTC) with a temperature-compensated crystal oscillator (TCXO) and crystal integrated into it.  The module integrates a coin cell battery input which helps it retain date and time even when the main power to the device is interrupted. It maintains seconds, minutes, hours, day, date, month, and year information, automatically adjusting the date for months with fewer than 31 days, including corrections for leap year. It can be set to operate either in the 24-hour or 12-hour format with an active-low AM/PM indicator. It has been used in several projects on this website mostly, due to its accuracy, and its low power requirements which help it keep time accurately, for a longer period of time compared to other real-time clocks (RTC) modules.

Another key part/component that we will use in today’s tutorial is the Arduino Due. One of the important things, when designing electronic systems that have displays is ensuring, that there is no flicker or lag when updating information on the screen and one of the best ways to ensure that, is to use a fast enough micro-controller. Putting this into consideration, for this project, we will use the very fast Arduino Due board. The Arduino Due has one of the fastest CPU in the Arduino family. The Due runs on an 84MHz CPU compared to the 16MHz CPU speed of the Arduino UNO, and as such, it is able to update the screen without any visible flickering.

The most important update to the previous project, however, is the 3.2″color LCD display being used. The display gives us the ability to create a better, bigger and colourful user interface for our clock at a cheap price as it costs about 7$ on banggood.

The goal for this project is to build a real-time clock with a user-friendly interface capable of displaying (without lag or flickering) the current time, date, temperature including the minimum and maximum temperature recorded in a particular environment over time.

The 3.2″ TFT, like most other TFT displays, comes as a shield which can be easily mounted on the Arduino Due. This, however, makes it difficult to access the IOs of the Arduino after the display has been mounted, as it tends to cover the front face of the board. To solve this, so that the DS3231 module can be connected, male headers are used (after bending them as shown in the picture below) to connect the RTC module to the Arduino.

To easily write the code for this project, we will use two libraries: the Bodmer TFT HX8537  library for the TFT display and the Sodaq DS3231 library to easily interface with the DS3231 module. Both libraries can be downloaded via the links attached to their names above. The Bodmer library is a version of the UTFT library specially modified for the Arduino Due as this particular display is incompatible with the UTFT library.

Next is the void setup function. We initiate communication with the RTC module and Initialize the display, setting our preferred orientation for the display and print the UI to the display.

With this done, we move to the void loop function. Under this function, we write the code to update all the parameters (after specific intervals) on the display including the min temperature, the max temperature, time and the date.

That’s it for this tutorial guys, there are several useful projects that can be built using this tutorial as a foundation. You could decide to add a buzzer to the project to create an alarm clock or make a to-do list based project, all out of this.

Alibaba.com offers 488 arduino tft display products. About 67% % of these are lcd modules, 5%% are integrated circuits （old）, and 1%% are digital signage and displays.

It"s based on an RGB TFT display controlled by an ATtiny814. It uses a crystal-controlled oscillator to keep accurate time, and takes advantage of the routines for reading from a TFT display described in my earlier article Reading from a TFT Display.

This started as a demo program for my TFT Graphics Library with support for reading from the display, but it grew in complexity, so I decided to write it up as a stand-alone project.

Without the ability to read back from the display you would have to redraw the whole display every time the hands move, which will be once a second if the clock has a seconds hand. This would require a fast processor.

This clock avoids the need to do this by using the ability to read from the TFT display to exclusive-OR the colour of each hand onto the image of the clock face. When the hand moves, you can remove it from its last position by drawing it again, which will restore the background to its previous state. This ensures that features under the hands, such as the hour numbers, aren"t wiped out when the hands pass over them.

The clock is designed to work with a 240x240 or 320x240 RGB TFT display available from AliExpress. I"ve also made a lower-resolution version that will work on a 128x128 or 160x128 display; see Lower resolution version. The following displays are suitable:

Unfortunately Adafruit displays aren"t compatible with this application, because they don"t support reading from the display; there"s more information about this in my article Reading from a TFT Display.

The clock uses the ATtiny814 Real-Time Clock to generate an interrupt every second, with the timing controlled by a 32.768kHz crystal. For the crystal I used a low-cost cylindrical clock crystal L - CS), where CL is the load capacitance, and CS is the stray capacitance which is usually estimated to be 2.5pF on a PCB. This gives C=20pF.

I have been using an earlier version of the Arduino IDE, therefore in the interests of simplicity, I recommend that you download Arduino IDE version 1.06 on your desktop machine before you install the code. You can get his version from here .

These need to be downloaded and added to the IDE (Integrated Development Environment) that runs on your computer, used to write and upload computer code to the physical board.UTFT.h and URtouch.h located in zip file below

(a) Sainsmart - If you have purchased a 3.2" TFT screen that is branded Sainsmart on the back of the TFT device you will have found they have to modify libraries to resolve display issues. If you have purchased a Sainsmart TFT Display already there is a fix below

(b.) TFT Controller Chipset - People who have purchased a 3.2" TFT screen may find they could also have one of two different chipsets "SSD1289" or "ILI9341" The annoying thing is that it"s not easy to distinguish the difference online. The good news is that its easy to fix. If you get a blank screen after loading the code then it"s probably because it"s an ILI9341 controller.

There are a group of bitmap files that I have included below that need to sit in the same subdirectory as the Arduino code when you begin to load into the Arduino. Therefore download the files below and use the IDE to load.

The Sound module is used to provide the Alarm. The ISD1820 is controlled by the Arduino D8 pin. Sound can be easily added by playing sound into the microphone while simultaneously pushing the record button on the ISD1820. In my case, I recorded the original Pac-Man introduction music from an audio file played through another device. Once the sound is recorded the recording can be tested by pushing the PLAY-E button which should play the sound through the speaker. Use the setup menu to set the clock time and the alarm time a few minutes apart. Be sure to "SET" the alarm and push the "SAVE" menu buttons. Once back to the main screen the Alarm should sound when the time occurs. Turning off the Alarm can be done by pressing the center of the touch screen panel resulting in the Setup Screen.

Some makers have found that the Buttons on the Setup Screen do not align with the TFT touch controls. In these cases the Touch Screen needs calibration. This can be easily done by using the Touch Screen Calibration code and instructions provided in the URtouch library. Follow these instructions if you observe this issue.

Recently, I learned Arduino for the first time and built a digital clock with Arduino Nano module + DS3231 module + 1602 LCD screen + rotary coding switch.

Compared with the previous version without shuttle adjustment function, a rotary encoder with switch was added on the hardware this time, and the connection between the LCD module and Arduino NANO was also adjusted.

The Arduino development software USES version 1.6.7, which can be downloaded from the Arduino official website. The address is as follows:https://www.arduino.cc/en/Main/Software?setlang=cn

1. When running normally, press the switch and the clock will stop running. A "N" character will appear on the display screen for confirmation bit (the 10th character bit in line 2).

4. After confirming the position of "Y", press the switch, the previous date and time change will be saved immediately and take effect, and the clock will exit the adjustment mode and return to normal travel time;

Alternatively, after confirming the position of "X", press the switch, the date and time changes made will be ignored, and the clock will exit adjustment mode and return to normal travel time.

We were already playing around with LED MATRIX for time and temperature display with a Wi-Fi connection on an ESP8266, but we didn’t create yet a project with an RTC (Real Time Clock) module and an 1.8 inch TFT display; here we go. We will use again a ready to go code, but we will change it a bit for better looking. SO, we will learn How-To code rectangles and lines for a TFT screen, very easy… It is GOOD to try out different components to get used with coding, Maker, MakerED… Especially when we use displays, which ever ones, as one sees directly the results; sensation of direct success!!

The tutorial in the video shows an Arduino UNO, but we will use in this tutorial an Arduino NANO as it is less expensive (+/- 1/3 of the price of an Arduino UNO) and also it takes less place when integrating the components into a box.

As you can see above the “Arduino IDE” shows an error and highlighted it in Line 1. The sign “<” is too much, delete it and save your sketch, then upload it again to the Arduino NANO. You might get a second error message again, check below please.

There are some problems with the time and day still… I didn’t follow step-by-step instructions on the video, OK let’s have a look in deep now!! Please check the video tutorial @ 03:15 for the settings and follow them strictly, otherwise your clock setting will NOT working!! Done so, it will be working great. I did some more changes in the coding such as changing the text colors and ALSO to draw a rectangle and some lines to make it look BETTER, please check below.

As you can see, I added some new code snippet from lines 142 to 151, this will draw a rectangle around the TFT screen and it will draw white lines under the measured values. It will look BETTER, well that’s what I think and my wife as well; you just do the way as you want, up to you
