| | Re: IR for bots
|
| (...) If you don't modulate the signal you run the risk of having another 40kHz signal (a.k.a. remoth control) trigger the reciever. If you modulate it and look only for you modulation code, then the chances of a stray signal are minimal. I have (...) (27 years ago, 28-Mar-97, to lugnet.robotics.handyboard)
