CMOS Toggle Flip Flop Using Laser Pointer circuit

Posted on Feb 6, 2014

The IR photo transistor Q1 (Radio Shack 276-145A) or similar is connected to the set input (pin 6). The photo transistor should be shielded from direct light so that the voltage at the set input (pin 6) is less than 1 volt under ambient conditions and moves to more than volts when illuminated by the laser pointer or other light source..
