Started off trying to introduce my son to programming, ended up with a working arcade machine, as you do!

The arcade machine is mostly designed by my son, it is just large enough to get the following components inside to make a working mini arcade if you use thin wire and have small fingers to stuff it all in (and fix anything internally with a some hot-glue) !

The follow electronics are needed for the working machine approx 8x4x4cm :

Adafruit Pro Trinket Adafruit Pro Trinket LiIon/LiPoly Backpack (battery charger add on) 150mAh LiIon battery square 0.95" 96x64 RGB 65k Colour SPI OLED LCD Display 3 x 7mm SPST Small Mini Micro Momentary Tactile Push Button Switch High Quality Miniature 2 Position Slide Switch SPDT 3-Pin On/On

(Ebay for these is about £25).

Wiring is shown in the included wiring.png file, not I'm not sure which combination of the buttons we wired up for left/right/fire with the included software so try before you fit it or adapt the software afterwards.

I've included our Arduino source as well if you are interested, three basic games are included! (Yes there are probably bugs, its just a bit of fun....). This uses 50% of the ROM for the trinkets 28K ROM, a good amount of the 2K RAM is also used, I'm sure you can fit a few more games in there though...

This page is great to show you how to set up your IDE environment to build and program the device for the necessary libraries we use here, see https://learn.adafruit.com/animated-flying-toaster-oled-jewelry/overview

Enjoy!
