I am starting a project on Arduino - a laser tag. I have looked through a couple of tutorials and still there are some items I can't quite understand.
My question i the following. In order for the receiver to get the signal it has to have the right frequency, that is, say, 38kHz. This means that I need to turn the LED on and off with the period of (1/38 000) s.
So using Arduino, I code a function that will wait for this time and then light the LED. However, how precise is arduino? Can it actually carry out the procedure so accurately?
