lcd displays remote control codes free sample

The remotes which we use in our home are basically made of IR transmissions for example TV remote, DVD remote, Sound System remote etc. But these signals never interfere with each other because every key in the remote control has unique operation code in Hexadecimal format. By decoding these signals we can know what is the unique code of the key. By knowing the codes we can implement several applications where we can control with same remote.

IR remote has a button and a microcontroller with IR LED attached. When a button is pressed, a microcontroller identified the button and sends the corresponding modulated signals (codes) to the IR LED. Then, the IR LED sends it to the IR receiver in the appliance.

System in the appliance demodulate the signals(codes) and the checks the function corresponding to it and executes it. Each function has a different code.

There are Multiple use of the Project:-You can display IR Remote signal and Decode and display it on LCD if it is not assigned in the ProgramWhen you press serval button you can show any character on LCD using different button"s.You can also run multiple function by assigning in Program.

This instructable provides the information needed for you to build a compact, touch screen, Infrared, remote-control unit that can be easily programmed with control codes cloned from your existing remotes.

I started this project for several reasons, the most significant being that the remote-control unit for my multimedia receiver is beginning to fail. Several of the heavily used buttons are intermittent and many of the receiver’s functions are only accessible by using the remote. Reason number two is that it takes three (3) remote-control units just to watch TV! The TV remote, cable box and sound system remotes are each required. Oh, not to overlook the DVD remote-controller so that would make four (4) remote units. Finally, I thought this would be an excellent project to learn a bit about Arduino micro controllers, writing a “Sketch” (the operational program) and how IR (InfraRed) remote-control units work, all new to me.

Fortunately, I found some excellent information that allowed successful completion of this project. The authors of the Arduino libraries used to compile the remote-control Sketch provide good background information that helped greatly in getting things to work correctly. My build has now been in constant use for several months.

The success of this project depends on remote-control protocols being supported by the Arduino IR2Lib library used to compile the sketch. The current version of the IR2Lib library seems to have support for a large number of equipment manufacturers but there is always the possibility that an IR remote-control device youhave is not supported. The authors of the library do have a technique for handling “raw” control data if there is no standard protocol support available but using this “raw” data technique is not within the scope of this Instructable.

The example “Dump” sketch provided with the IR2lib library should give a quick answer about support for YOURremotes. You may have to try 2 or 3 button presses to get a successful result. I suspect the IR (infrared) receiver is sensitive to electrical noise and, perhaps, ambient light.

Note-when pressing the button on your remote, do it firmly but quickly! It seems that some remotes send a special “repeat” code after the desired function code if the button is pressed for too long of a duration. This may cause “Unknown” protocol results.

Once you know the protocols used by your remotes are supported, you can continue with confidence that you will have a successful project. If you only get a protocol type as “unknown”, well, it will take an adventurous individual to try and work with the “raw” data and is, perhaps, the topic for a new Instructable but not within the scope of this project. The IR2lib library does provide examples and instructional information about using "raw" IR codes.

I have tried to provide thorough documentation with many diagrams, photos and lots of comments within the Sketch (program code) but this project might be quite a challenge for a beginner. I recommend reviewing the steps that follow and read through the Sketch (bp_remote.ino) since the comments in the Sketch provide a lot of information.

An assembly drawing for this circuit shows where to place the components on a typical perf-board. Also provided is the artwork to make your own PCB (printed circuit board) if you choose. There are several sources for information about making a PCB at home. Several “Instructables” (do a search for “PCB” within the “Circuits” group) as well as many on-line videos such asthis video and others offer techniques for getting the job done. Do an on-line search for “how to make a PCB at home”. Of course, the PCB approach is optional. Point to point wiring on a perf-board will work nicely if the provided layout is used. Remember, it must fit into the remote-controller’s case. During the development of this project, I first used a perf board with point to point wiring but decided to add PCB fabrication to my learning challenge. My final assembly did make use of a home-made PCB.

Can point the Universal Remote at the TV or another device you are trying to control during programming. If this "link" is broken, you will have to restart the programming process.

Specific programming options and steps may vary with each universal remote control brand and model. The following are examples of options you might see and steps that may be required.

The easiest way to program a Universal Remote is to enter a code that identifies the product you wish to control. Codes may be provided via a "code sheet" or a web page where the codes are listed by brand and type of device (TV, Blu-ray Disc player, Home Theater Receiver, Cable Box, VCRs, and sometimes media streamers).

Press and hold the appropriate DEVICE button on your Universal Remote Control (some remotes require that you press a Setup button before pressing the device button). The LEDs for the device and power buttons will light up.

Although the buttons may be labeled for a specific device, you can use them for any compatible device; you must remember which one corresponds to the device you are controlling.

With the device button on the remote held down, ENTER THE CODE for the brand of the device. If a brand has more than one code, start with the first one. As you enter the code, the power button on the remote will turn off.

After programming, see if the universal remote controls the basic functions of your device. For example, a universal remote should turn a TV off and on, change the volume, channel, and source input.

You can use Auto Code Search if you don"t have access to the specific code for the brand or type of device you wish to control. The Universal Remote will search through its database, testing several codes at a time.

Press and release the DEVICE button on your remote associated with the product you want to control (TV, etc.). As mentioned previously, you can use any device with any of the labeled buttons—remember to write it down.

Press and release the PLAY button on the remote, then wait a few seconds and see if the device you are trying to control turns off. If so, then it has found the correct code. If your device is still on, press the play button again and go through the waiting and turn off process. Do this until your device turns off.

Next, press and release the REVERSE button on your remote every two seconds until your device turns back on. When it finally does, the remote has successfully searched for the correct code.

Press and release the Power button repeatedly until the device you are trying to control turns off. If the device turns off, the Universal Remote has found the correct code.

If your device doesn"t turn off and the LED light blinks four times, this means you have exhausted the codes for that brand, and you need to use another programming method.

Instead of having the remote scan through all, or brand, codes automatically, you may also be able to program the remote by having it check each code one at a time. However, keep in mind that this process can take a long time since there are so many codes.

Press and hold the corresponding DEVICE and POWER buttons on the remote at the same time. Wait until the power button comes on, and then release both buttons.

If your device fails to turn off, press the Power button again so that the remote tests the following code in the database. Perform this step until it finds a code.

If supported, the IR learning method requires placing your universal remote and the remote of a device you wish to control so that they are pointing at each other. This process allows IR control light beams to transmit from the original device remote to the universal remote.

Activate the learning mode for your universal remote. If there isn"t a Learn button on your remote, you will need to consult the user guide to determine which one performs this function—not all Universal Remotes support this option.

Repeat these steps for every function you wish to duplicate (such as volume down, channel up, channel down, input select, etc.) on your universal remote.

This process is long and tedious, especially if you have several devices you want to control. However, if you don"t have access to the remote control codes or other methods fail, you may be able to use the IR learning process as your last result, provided your Universal Remote supports this programming option.

Instead of searching for the correct code, you plug a Logitech Harmony Remote directly into your PC via a USB connection. Then you do all your programming online through the Logitech Harmony website, which not only has a continually updated database of about 250,000 control codes but saves all your programming setup preferences for easy access when needed.

A universal remote is not always an entire replacement for your original remote. Some only control basic functions, while others may provide access to advanced picture, sound, network, and Smart TV or home control feature settings. However, you may still need to use the original remote for some or all advanced features, so store it and some batteries, where you can easily find them.

Check if the remote has a temporary memory that stores control information for a few minutes when changing the batteries. Otherwise, you may have to reprogram the remote.

As mentioned at the top of the page, programming options and steps may vary from one Universal Remote Brand/Model to another. Consult your user guide for specific details.

To program an RCA universal remote that doesn’t have a Code Search button to work with any TV, turn on the TV, aim it at the TV, and press and hold the TVbutton on the remote. Keep holding the TVbutton when the light turns on and then press and hold the Powerbutton on the remote until the light turns off and on again. Next, press the Powerbutton on the remote for five seconds until your TV turns off. The TV turns off when the remote finds the correct universal code. You can also use these directions to program an RCA universal remote to a DVD player without codes.

When you want to program your GE universal remote to your TV but don’t have the code, turn on the TV and press the Code Search button on the remote until the indicator light turns on. Next, press the TVbutton and then press the Powerbutton until the TV turns off. After the TV turns off, press Enteron the remote to save the code in the remote.

If you don’t have the code for your Philips remote control, turn on your TV, look for the Setupor Code Search button on the remote, and hold the button for 10 seconds. Then, press the TVbutton on the remote and press the Upor Downbutton until the channel changes. When you can change the channels, press the Powerbutton on the remote to turn off the TV and complete the programming.

If you don’t know your Jumbo universal remote code, you must use the code search function. To begin, turn on the device you want to control, aim the remote at it, and press the Code Search button until the light stays on. Then, press the button for the device you want to program. When the light on the remote stays lit, press the Powerbutton on the remote until the device turns off (you may need to press the Powerbutton several times). After the device turns off, press Enteron the remote to save the code.

Imagine if you could extend your Digital Signage screens right onto your audience’s hand held devices, allowing them full control over which content to watch and to make selections; well imagine no more, RemoteTouch™ can do all that and a lot more. With RemoteTouch™ a visitor can simply pull out their hand held device (like a tablet or phone) and scan a QR code that’s displaying inside your Digital Signage presentation.

As soon as your customer scans the QR code, his mobile device will open an HTML page that will allow your customer to make selections and in turn, control your designated digital Signage screens remotely; essentially converting your audience’s hand held devices to a kiosk so they can choose which content to watch and for how long. Let’s use an example scenario, a customer walks into a Hobby Shop, he is not sure if he wants to buy a remote control car, RC plane or RC boat. When he walks around he notices a QR code which is displayed on one of the Digital Signage screens titled: “Scan me to control this screen”. The customer pulls out his iPhone and uses a QR reader App to scan the screen. This opens up a web page where he can select which presentation he would like to watch. The selections include RC Cars, RC Boats and RC Planes. As soon as the customer clicks on one of the HTML buttons on his iPhone (or Android, it doesn`t matter), all of the designated Digital Signage screens at the store would begin playing the presentation selected. But that’s not all, with RemoteTouch™ the customer can even make further selections in sub pages, and navigate individual products using for example LEFT / RIGHT arrow buttons on his device which in turn will flip through products on the screens. And the best part, MediaSignage provides all the tools to create an engaging RemoteTouch™ service and you don’t need any programming skills at all. In fact, you can setup RemoteTouch™ in a matter of minutes, controlling which presentations and what screens may be controlled by your Audience.

RemoteTouch™ fills the gap between the Digital Signage world and the Mobile world, finally allowing your customers the freedom to engage with your screens in a natural and convenient way. RemoteTouch™ is an intelligent service that is packed with great features, for example, if a customer is controlling a screen, that customer would receive exclusive access to that screen until the presentation ends, or until he exists his selection, thus allowing others access to RemoteTouch™. RemoteTouch™ is also intelligent, so it generates a unique QR that is bound to a specific screen, so if you have dozens of Digital Signage screens in different locations, the system is smart enough to know which QR was selected and allow your customer to control only the screen they are standing in front of; all this requires no special configuration on your part, it’s just smart like that. And there is more, with RemoteTouch™ you can load our default HTML selection page so you can get up and running in no time. However, you can also host an HTML page anywhere you like and this page can be used instead, to present your audience with a fully customizable selection page.

RemoteTouch™ is truly a revolution in technology as it was the missing link for true synergy between Digital Signage and Mobile. We think everyone will agree that allowing your customers to control the screens and make selections not only serves the best interest of the business, but also delivers targeted content which your audience will love. So to summarize, with RemoteTouch™ your audience can use their smart phones to scan a QR code and remotely control the screen in front of them. When users tap on the menu displayed on their mobile phones, the corresponding content will be presented on the Digital Signage screens; it`s simple and works.

1.If it is not used for a long time, remove the battery to avoid leakage liquid of the battery to damage the machine. When the LCD looks dim, please change batteries. (Newold batteries can not be used together) After the batteries are replaced every time, it is not necessary to set model code again.

If your DIRECTV remote stopped working or is just not responding, a simple reboot may resolve the issue. Here’s how to reset your DIRECTV remote control.

Move anything that could be blocking your remote’s infrared light from reaching the receiver’s sensor. Even the glass door on your entertainment center can cause interference.

Using a microfiber or other lint-free cloth, wipe away any greasy fingerprints or nacho cheese streaks from your remote’s emitter and the receiver’s sensor.

Keep your receiver and remote out of direct sunlight. Also, try turning down the brightness on your TV. Bright light can interfere with your remote’s signal.

Depending on how long you’ve been a customer and what equipment you have, you probably have one of two DIRECTV remotes: a standard universal remote control or the DIRECTV Genie remote.

Your DIRECTV universal remote control can control up to four devices, including DVD/Blu-ray players, DVRs, gaming consoles, soundbars, and TVs. Here’s how to program your remote for both SD and HD receivers and how to change your TV’s input source.

Select the device (DVD/Blu-ray player, DVR, gaming console, soundbar, TV, etc.) that you want the remote to control. If your device isn’t listed, enter a DIRECTV remote code. Find them by using this code lookup tool.

If you have a Genie remote, there are both automatic and manual pairing processes—plus a third option for DIRECTV Ready TVs. We’ll start with the automatic pairing process.

A DIRECTV Ready TV, when connected to a Genie DVR, allows you to watch DIRECTV without an extra Genie or Genie Mini. Here’s how to pair a DIRECTV Ready TV with your Genie remote:

If your remote still won’t work with your device(s), visit DIRECTV’s remote troubleshooting page or contact DIRECTV technical support at 1-800-531-5000.

DIRECTV charges $15–$25 for a new remote, depending on whether you have the universal remote (the white one) or the Genie remote. If you have DIRECTV’s protection plan, the company will replace your remote free.

You can, however, find DIRECTV’s remotes on Amazon.com for far less than $15–$25. A two-pack of DIRECTV RC73 IR/RF Genie remotes is currently $11.75. A DIRECTV IR/RF Universal Remote Control (model RC66RX) is $6.75, and a two-pack of the same remoteis $12.00. Both include free shipping through Amazon Prime.

You can use your phone or tablet as a DIRECTV remote via the DIRECTV app, which currently supports the receiver models HR20, HR21, R22, HR23, HR24, HR44, H21, H23, H24, and H25.

Reasons that your DIRECTV remote might not work include dead batteries, stuck buttons, faulty parts, incorrect mode settings, receiver location, blocked sensors, and other problems. We suggest visiting DIRECTV’s remote troubleshooting page for solutions.

For example, to program your DIRECTV remote for a Samsung TV, you would follow these instructions (link leads to the list in this article). In Step 3, you’ll use the lookup tool to find the TV codes make and model of your television. It’s not unusual to have several codes for the same television. Try each code until one works.

DIRECTV does not have voice remotes, but there is limited voice functionality in the DIRECTV app. You can also control DIRECTV through your Alexa device (Echo, Dot, or Tap).

One of the major features of Zoom is its support for screen sharing and remote access. If you are running the Windows desktop app, participants can take control of each other screens in order to provide support or show guidance (it"s just one of many cool features on the Zoom platform).

It doesn"t just specialize in screen-sharing and remote access. The software also lets users transfer files between connected PCs, conduct web conferences, and make online presentations.

Unlike some of its competitors, the software also allows group sessions. When in a group session, you can easily pass control of a machine between users, rather than only allowing a one-way session.

Chrome Remote Desktop has one glaring drawback—both computers need to have the Chrome browser installed. If you use an alternative browser, you should look elsewhere.

However, if you use Chrome and you"re looking for an easy-to-set-up, no-frills remote access tool, you would struggle to find a better option. Google has aimed the software at home users who need to share computer screens for some quick troubleshooting or file access; it lacks the advanced features of some other options on this list.

Alternatively, you can head to remotedesktop.google.com and make the connection via the web app. The extension has slightly more features, such as an extended list of supported keyboard shortcuts.

Beginners might also find the app difficult to set up. If you want to connect to machines outside your home network, you need to know the IP address of the person you want to connect to and configure their router to accept incoming remote desktop connections.

Ultimately, it"s important to understand Microsoft Remote Desktop is designed for office use, not home use. If you want to troubleshoot a family member"s PC, look elsewhere.

Unlike TeamViewer, however, it does not require any installation. You just need to run the 2 MB EXE file and follow the on-screen instructions. It means you can keep a copy on your USB flash drive and instantly provide remote access to any machine you are sitting in front of. You can make a connection using your computer"s IP address or by sharing the automatically-generated passcode.

There"s also an option to set up unattended access. It"s great if you want to access your files remotely without a person"s physically using your other machine.

Other features include an adjustable slider that balances connection quality with connection speed, clipboard syncing, remote session recording, and cross-computer keyboard shortcuts.

SkyFex is an online remote access service. That means it doesn"t require a download—it"s entirely browser-based. It also means that SkyFex is accessible on all platforms, making it a nice choice for those who are looking for an easy tool to use to help clients or even just friends.

If you don’t have access to the specific codes for your devices, brand code search is another option to program your remote. Like auto-programming, brand code search allows you to look for a specific device code using your remote. The difference here is you will need to know the brand code of your device or look it up online.

No matter which option you choose, remember to check that your remote has batteries before you start programming. And, make sure you can point your universal remote at the device you’re connecting to; otherwise, you won’t be able to program your remote.
