Toggle Flip Flop Laser Pointer Using CD4013


Posted on Feb 6, 2014    11157

The circuit below is similar to the one above but can be used with a laser pointer to toggle the relay rather than a push button. 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.
