When I was at Big-Brained Superheroes on Monday, I noticed that the kids were aiming the flashlight at the robot from above. So why not have a light-following procedure that responds to light shined from above?
After some somewhat sloppy soldering (keep telling yourself it’s only a prototype), I implemented this breadboard-hole-conserving design for a third photocell which will be aimed upward:
It will fit into the breadboard like so:
Tomorrow, I’ll try to get done with the computer/robot software to implement the light-above procedure. Demo to come.
