Subject: [alt-beam] IR Obstacle avoidance
I haven't played around with IR too much, but I was just wondering what kind of range I can get if I use IR photodiodes (no lense) and bounce it off a WHITE wall back to the reciever. I will have pulsed IR of course - probably the same frequency as a TV remote since I have a bunch of recievers with that frequency (I forget what it is at tyhe moment).
