Cut and paste the code below, and then burn it to the Arduino. Now that we have installed the NESpad library correctly we can test out our connections to our controller. Please head over to Libraries - Arduino Reference for better instructions on installing libraries. If NESPad is not on this list then you installed the library incorrectly. Now start the Arduino IDE up and Click Sketch -> Import Library -> NESpad. You might want to also copy the contents of the examples folder to ArduinoHome/examples. Copy the zip file to ArduinoHome/libraries and unpack it. At the time of writing this is version 1.3. So head over there and download the most current version of the library. Here is the link to that project Google Code Archive - Long-term storage for Google Code Project Hosting. Instead of rewriting all of the events by hand I used a current NES Library (NESpad) in my sketch to capture the events. Make sure they get pushed in all of the way though. Should be pretty easy to do, because the wire can just be pushed into the NES controller for prototyping. This is the general pin layout for the NES controller, along with the Fritzing wiring diagram. Lastly we will capture these serial output events in a Java class and then use the Java Robot class to convert those Serial Outputs to actual keystrokes, which we can then map to any NES Emulator. Then we will write an Arduino Sketch that will output the keypress and keyrelease events from the NES Controller. First we will wire up the Arduino to an old NES Controller. So at a very high level this is what we are going to do. What I wanted to do was to actually be able to control a NES Emulator on my computer.

Most of the tutorials I found online were only “How to control leds with your NES controller?” or the like, but this isn't what I wanted. The main portion of this project was actually figuring out how to actually control a NES emulator with the controller once we were done wiring. My hope is that I will save someone time and energy hunting down all of the specs and websites I had to do in order to get this project up and running. Hello this is my first week with my Arduino Uno and I thought I would take some time to write up a quick tutorial on my first project. I am hoping to finish it in the next couple of days.
