In this guide I’ll show you how to use the shield and it’s two buttons. Lets get to it.<\/p>\n

Resoltion is 64×48
\nButton A is by default pin D3.
\nButton B is by default pin D4.<\/p>\n

Buttons can be customized by soldering jumper pads under the shield.<\/p>\n

PS, be sure to get the shield with A & B buttons when you buy it, there are a few types to choose from.<\/p>\n

Code:<\/strong><\/p>\n

There are several libraries to choose from, but I found the one from Sparkfun<\/a> to be suitable for my use.<\/p>\n

Download it, then unzip in libraries folder and restart Arduino IDE. Then paste my code:<\/p>\n
