555 timer - 1200hz square wave generator?
I would like to replicate the Hitechnic IR Beacon. Essentially, this means that I need to create a 1200hz square wave. I would like to do this with a 555 timer, a 3v power source, and infrared LEDs (1 - 3). Please offer any suggestions you might have. This will work in conjunction with the Hitechnic IR Seeker and an NXT Bot that I will program in RobotC.
