This is PART-2 of the Tic-Tac-Toe PIC16F627A project. On PART-1 I described the circuit operation, and the basic program flow. In this new section I will propose a possible “good looking” enclosure build for the device with large back-lit buttons. Here you will also find the links to the PCB, Hex code, Assemby (ASM) code, and the .cdr file for laser cutting the top panel.”
