Hi guys,
I have an ordinary ir emitter and an receiver(just the LEDs with two pins). I managed it to send its signal to a pin on the arduino and am now able to control things like a led glowing when path obstructed. But I have no idea at what freq. the ir is transmitting. But I want a method to control the ir led to produce at an certain kHz. How do I do it using arduino?
Thanks for the help, in advance
