Hello guys.I'm having InduinoX clone of arduino.It has an inbuilt IR led to pin D14.But all examples using IR send are configured to pin 3.How do I reconfigure the pins?
If you are looking to emulate an IR remote control, you will almost certainly need to drive the IR LED at 38KHz. The usual way to do this is to set up timer 1 or timer2 to do this, which limits you to using pin 3 or pin 9. To use pin 14, you would have to write code to toggle that pin every 13us instead.
Would you plz explain bcz i'm a learner.
