Multi-player retro gaming on an Arduino VGA console
When you’re introduced to an Arduino Uno, perhaps you want to take button inputs, control a few LEDs, or move a hobby servo motor. These boards are quite good at that, but with some creative coding, they can actually control a VGA monitor and even play low-resolution games like Pong, Snake or Tetris.
Using Sandro Maffiodo’s VGAx libraries, Instructables user Rob Cai built his own gaming setup, wiring the controls into two separate units. Now, while the base unit hooks up to the actual screen and takes inputs from player one, the second allows player two to participate as well.
I decided to split it in two units: one with a potentiometer and four buttons for the single player games, the other with one button and the second potentiometer for the second player. Thus in total you need 5 buttons, two potentiometers, a VGA connector (DSUB15 female) and, of course, an Arduino! Most importantly, there is no need of supporting IC or special shields!
