This is very simple and fun project with very few external components. All PONG game is controlled and run by 8 pin PIC12F675 microcontroller that is clocked with 4MHz internal clock generator.
Schematic is made of few components where Video output is combined of two resistors that form simple DAC compliant for TV video 75Ω input. Control part consist of two potentiometers for positioning on screen and trigger button. Schematic is assembled on a prototype board – so you can really amaze your friends by connecting this video game system and start playing. Source code works for PAL625 system and can be compiled with gpasm compiler. Or simply download precompiled hex file.
