How to use Arduino as TV Remote Controller with Infrared

[@robojaxsupport3013]

Please follow the instruction in the video and open the example. Then follow what I have said in the video. it for sure will work.

[@AugustineAriola]

I have problem decoding the remote codes. Each button doesn't give me a unique hex code. Each time I press a particular button it give me totally different hex value. What do I do ?

[@robojax]

try another remote. different type.

wtf

[@srujanendhratalla4187]

guys if it shows error: missing terminating " character use one backspace on the error line and for empty character constant error give a space bar gap between the ('') instead use ( ' " ) this should do the trick. The code on the website has formatting issues hope it helps you guys it took 2 hours to find what is wrong.

how can i change my sketch so that i can also add buttons for volume to go along with my power button

sorry I didn't get. if you want to send two signal you can do it But the TV needs some time like 1 second delay between them.

if it doesn't work, put your receiver in a box and cover it with aluminum foil, also shut down any light source. this solved it for me. i guess it blocks the noise from other devices

[@robojax]

Hello, then you need to use just a receiver and detect it without the library. Or check the library if there is such feature. I make this series of videos because many people needed to decode the remotes.

[@elektrotehnicar]

I don't think it's working. I've done exactly the same thing as you and I don't see it blink on my phone camera, but it was on when I connected it to direct 3.3V.

AYUDA!!! Hola, buenas. Estoy haciendo un proyecto con un Arduino Mega y se me esta complicando el uso del Led Infrarrojo (emisor), para comunicarse con mi decodificador de DirecTV. al usar el lector infrarrojo, me aparece el codigo pero no especifica si es NEC o SONY, etc. Alguno tiene un codigo tipeado para compartir que sea, por ejemplo, cambiar de canal del decodificador de DirectTV? nota: En el proyecto ya tengo utilizado casi todos los pines, en lo posible, el codigo deberia tener la ubicacion del sensor y no colocarlo en el pin que deberia estar por defecto de la libreria, (que si mal no recuerdo, en mega es el pin 0). desde ya muchas gracias!!

[@SimpleEnough2k9]

It's pretty impressive to see how much work is done behind the scene by things we're taking for granted every day. Although they're using the same media to communicate, infrared in the actual case, it seems that manufacturers are being assigned specific codes whenever they're using a more common protocol. It's surprising to see that there are so few IR codes duplicates, if any, between different manufacturers, even if they're using the same protocol. Globally speaking, having all these IR remotes working so seamlessly in our daily lives is simply amazing. The idea you presented, around 09:50, would be a nice to have for an intelligent remote but since there is no possibility to query the input currently in use, the actual volume intensity or if the on/off state of a given device therefore programming a successful sequence of commands would be simply pure luck. The only way to somewhat get around this situation would be to track the remote controls activities thus knowing which input was used last or if a given device is on or off but again, nothing is perfect and there is no way to determine if the "tracker" missed a hit. A good example would be for the volume intensity; if someone is holding the key, the volume will raise or lower but we won't know where it will stop, unless perhaps there is a possibility to detect the "repeats" and determine if the device is actually supporting them. As far as I can tell, there are too many unknowns to create something reliable. Anyhow, thanks for your time and support.

[@robojax]

Than you for sharing your thoughts. Actually I used get away from IR remote because few years prior I tried it and it did not work as expected. But once I got both types of receivers I learned how to use them and detect them. Then I wrote code and created tutorials to decode any remote code, control DC motor, control Servo motor, Control relay and more . You can find my other videos kzbin.info/door/kcBSig_Iu4ZnAIeCeG1TVgsearch?query=remote

Hi my name is Denis...I need help with writing a code for my audrino project... I am trying to help my friend who is in a nursing home to improve quality of life... I am building him a IR remote that will have one button to perform 3 to 4 functions. At present in order for him to watch DVD he needs to select correct input on the TV before he can watch a DVD. His problem is that he can't navigate his TV remote to get to HDMI2 for example. I would like to setup one single button on an audrino that will transmit IR signal in timed sequence and navigate to desired input on TV. I managed to work out how to capture IR signal in HEX value from his remote... now I need help to program these IR HEX values to be transmitted in sequence to navigate to desired input using one function...?

Hi, i want to make a prohect that changes the code from a remote. So i can use a bang&olufsen remote on a Toshiba tv. Can this be done

Hi, you can use Arduino to read the code from remote A and you have to list or create Array for A-1=Volume UP, A2-voluem down, A3-channel up, A4 Channel down and the same for TV you have to have the remote for the TV we call it B and read the needed codes and save them.. then write the code so remote A key is pressed, you can send remote B's corresponding code. Doable but needs some work. good luck.

It is so hard, even small push will make robot fall. But we have been created by such supreme creator that human will never understand it fully. So first we have to capture for each commands of remote A. and then capture commands of remote B. then wire the code when remote A is pressed, send commands from remote B.
