First proof of concept test of an interactive led matrix using the "cheapswitch" interface method. Circuit is controlled by a pic16f628a microcontroller.
It's just a metal disk (a 5p coin in this case) which makes a connection between the 2 electrodes above each led, this is detected by the microcontroller and it turns on or off the corresponding led.
