the PIC12F629 on a microcontroller based electronic dice. electronic DICE with 14 LEDs dual membranes prepared for application software mikroc used to give random results when a button is pressed for 3 seconds if not used within 15 seconds after it goes to sleep mode normal operation of the circuit of the button continues. Electronic DICE circuit PCB Sprint layout prepared with ISIS simulation software source code that belong to the file and drawing.
