Infrared Beacon for Robotics

MissionPeak
This project is an Infrared (IR) beacon for use in some robotics games and competitions. It emits an IR signal at 1200Hz (adjustable ±200Hz) suitable for some IR sensors in robotics. It uses the LM555 timer IC and a two-transistor current source to drive IR emitting diodes. The device maintains stable frequency and IR output throughout a wide operating voltage from 4.5 – 9V independent of battery strength. A low/high switch selects longer battery life or higher IR output.
