Sun Light Chaser


Posted on Feb 6, 2013

With RFT illuminated, point R goes to 0 volt and LM runs. With LFT illuminated, point R goes to 0 volt and RM runs. With RFT and/or LFT not illuminated, points R/L go to +9 volt; P1 and P2 controls threshold point when RM/LM stop or start running. Remember to seperate FT1 and FT2 with a vertical cardboard wall in order to produce a shadow over the other FT whenthe first is illuminated by a lateral incident light.
