Yes, You can use other color LED. But please try on bread board first and then make on a PCB board.

Great work, but instead of making this circuit, place your remote in front of camera lens and you are done :)

Ya i had made a video on that too..You can watch the same in my YouTube channel.

This is a fun project i tried :)

Looks like fun. I just ordered the chips and the pc board. Should be putting one of these together in a couple weeks. Nice simple, useful project for a newbie like me. I've never messed with black pc board stock before. Looks like a good place to start. Thank you.

Nice, but it's way easier to just view your remote on a phone or tablet screen in camera mode or just on a digital camera's screen. Since their IR blocking filters cannot block ALL of the IR, it shows up as white. Push the button and you'll see it blink on the screen. Of course, you need to aim the IR output at the camera lens. Quick and easy.

Your right.. I have done both. I have the other video showing how to test the remote with a camera in my YouTube channel.
