Update to the previous Light follower robot! Now using 2 LM324n op amp ICs and an L293D half H-bridge IC, this circuit allows the bot to stop and even reverse when a light source gets too close, and move forwards towards a light source as it moves away. It is reasonably good at ignoring other light sources (as long as the light being tracked is somewhat brighter!) and is fairly smooth as well. Still completely analog as well!
Awesome! I was wondering why I haven’t been seeing a lot of BEAM bots. I know MCUs are so cheap and easy but figured there would still be people interested in this stuff.

Interesting will try to make it
What is this monitoring program you have on the right?
This is cool
gotta love an analogue controller circuit
It has a breadboard, it looks pretty analog to me. Doesn’t need to show waves.

robotic moth when?
