Multi-Invaders Game Emulator
Written by Larry Bank (bitbank@pobox.com)
Copyright (c) 2021 BitBank Software, Inc.
Project started July 2021

This Arduino sketch contains the code needed to emulate the original
Taito Space Invaders along with Galaxy Wars and Lunar Rescue. The project
does not contain any game code and instead will read the game code and data
from ZIP files provided by the user. The 3 ZIP files can be from MAME or
other emulators and must contain the following files:

Taking your nodebot wifi

Controlling your nodebot using a USB cable is great and all, and obviously you could shell out and grab a sparkcore or some other dedicated controller but what if you've got a standard arduino and you want to take an existing nodebot wireless?

Bluetooth is an option and there's this excellent JohnnyFive wiki entry that will help you there. Bluetooth can be a bit flaky though and it's range is pretty lousy. You can also look at things like XBees and what not using point to point serial, but these are expensive and very fiddly to get working.

Really, what we want is a method of transferring data over a nice, simple, standard method, requiring little configuration, low cost and we can utilise a whole stack of the code we've already produced.

Enter the WiFi232 module. These little beauties are [available from AliExpress for $12 each](http://www.aliexpress.com/item/USR-WIFI232-T-wifi-to-uart-tt

#define PIN 2
#define Pixels 25

// Parameter 1 = number of pixels in strip
// Parameter 2 = Arduino pin number (most are valid)
// Parameter 3 = pixel type flags, add together as needed:
//   NEO_KHZ800  800 KHz bitstream (most NeoPixel products w/WS2812 LEDs)
//   NEO_KHZ400  400 KHz (classic 'v1' (not v2) FLORA pixels, WS2811 drivers)
