led lights using analog flip flop circuit diagram

Posted on Feb 7, 2014

This will drive a total of 42 LEDs. It is based on the assumption that the forward voltage of your LEDs is ~2. 2V, and that they will be bright enough with a forward current of ~21mA. If yours are a lot different, I will have to modify the design. The 2n3904 is a general purpose NPN audio/switching transistor which should be similar to the one show
