Reverse engineering remote control helicopter IR protocol
Kerry reverse engineered the infrared remote control protocol used by a Syma S107G remote controlled helicopter. He took the remote control apart, probed it with a scope, and analyzed the signals:
This tiny remote control helicopter is a rather amazing toy. Not only its movement is very stable, but the rotor speed, forward backward movements and turning can be all proportionally controlled as well. I thought it might be interesting to take a look at its control protocol to see how things are done. And yes, I do have a video at the very end showing controlling the S107G using the reverse engineered remote control.
Arduino source code for controlling the helicopter can be found on his blog.This entry was posted in Arduino, infrared and tagged Arduino, IR protocol, toy helicopter.
