Control your LEDs with your TV remote?! || Arduino IR Tutorial

In this project I will show you how I repurposed the useless buttons on my TV remote to control the LEDs behind my TV. You can also use this technique to control all sorts of things with a bit of code editing. I will also talk a bit about the theory of how an infrared transmitter and an infrared receiver communicates with each other.

Ever wanted to use your TV remote to control your next project? Then you might find this video useful!

I have the opposite problem, whenever I change the volume on my tv, my led lights change to a really fast flashing light

me: YES HE HAS THE SAME REMOTE AS ME
him: *grabs a different remote*

You're a very talented man with a good sense of humour; even if you have strange accent! Cheers and thanks!

How have I not found this channel already..this is amazing

[Hardwarenerd]

Build options changed, rebuilding all

C:\Program Files error: 'TKD2' was not declared in this scope
 int RECV_PIN = TKD2; // the pin the IR receiver is connected to
                ^
Error compiling.

  This report would have more information with
  "Show verbose output during compilation"
  enabled in File > Preferences.


why  ?

[zaprodk]

Now, modify it so you can control the color :D

[rohandesigns]

The Arduino code is showing error during compiling.
It's showing

"C:\Program error: 'TKD2' was not declared in this scope
int RECV_PIN = TKD2; // the pin the IR receiver is connected to"

What does that means, can you help and how to debug this. Thanks

Fantastic. I always watch you channel. Have you thought of doing an automatic ad mute, where a microphone is monitoring the normal sound in the room, then when an ad comes on its much higher volume. so therefore a circuit will monitor the volume if its higher then mute using the appropriate IR code

Hi, i downloaded the library IRremote, and when i try to launch the example I have this error :

C:\Program Files error: 'TKD2' was not declared in this scope

int RECV_PIN = TKD2; // the pin the IR receiver is connected to

^

do you know how to fixe this please ? :)

[johnathaneilers]

"Well why this crap?"
Haha, this made me laugh so hard

[hannah-idny]

Today it happened when I was using the volume button the lights changed and I was so confused

[claralille]

Arduino: 1.8.2 (Windows 10), Board: "Arduino/Genuino Uno"

C:\Program Files error: 'TKD2' was not declared in this scope

int RECV_PIN = TKD2; // the pin the IR receiver is connected to

^

exit status 1
Error compiling for board Arduino/Genuino Uno.

This report would have more information with
"Show verbose output during compilation"
option enabled in File -> Preferences.

Getting this error, please help me out !

Very nice, simple and effective. I am thinking about total colour control using 3 mosfets, one per color and an extra button to switch between them.

[samuelmessiha]

I am thinking of right now and who better to explain then great Scott!

[flamesflames]

i love your work. I don't have an arduino nano, so how can i go about with the IR decoding without using the arduino nano? pls really need your help

[thedavinator]

Awesome project. I might try this if my dad lets me hot glue an LED strip to his tv stand lol

[fabbbio]

What about the voltage drop between source and drain on the mosfet when is "fully open" ? Have you measured it? Considering how much LED current (and brightness) is sensitive respect to the voltage variations, I think that it is an important parameter to check. If not, you can't reach the maximum brightness that the LED strip can achieve. However great video! Thanks for sharing!

Me: "Omg, what luck! He's going to use the same kind of remote as I have 😁 Now I can follow exactly what he does! 😊"
Him: **Placing it aside and starts opening up a different remote**
Me: "🤦‍♂️..."

Hello GrestScott, I have one question for you. I made similar coding just for relay on and off. On arduino uno it works just fine, but when I try sending it on attiny85, nothing happens. I made some project with attiny85 and thay all works so it's not problem in programing attiny. Can you help me pls??
