  • @WayneDavisRocks ...takes to discharge the capacitor in microseconds (very precise). the photoresistor will discharge the capacitor faster or slower depending on its resistance (which changes based on how much light is shining on it). These are the basics. These numbers can be wielded in your code to then tell your motor what to do (turn left or right). See this manual around page 222 for some good information. parallax.com/Portals/0/Downloa­ds/docs/books/edu/Roboticsv2_2­.pdf

  • @WayneDavisRocks I don't think I still have the schematic or code but the basic idea is to utilize photorestors. The photoresistor changes its resistance based on how much light is hitting it. So it there are two photoresistors, it can be found that one is facing light more head on than the other (if you have one facing left and the other facing right, for example). The photoresistor is put in line with a capacitor that gets charged by the basic stamp. The basic stamp can time how long it...

  • any chance you have the schematic and code for the stamp, I'm trying to build the same thing for a stirling generator that I built
