#RedButton

Folder structure

• Arduino -- code on Arduino (both code and WiFi library)
• iPhone -- iPhone Space Shooter app
• RedButtonAPI -- the iOS API to receive Arduino signal

How it works

First, connect Arduino UNO, WiFi Shield, Joystick Shield together Basic idea:

• When you press a button on Joystick Shield, Arduino notice that change and send the changes to WiFi Shield
• WiFi Shield send out UDP datagrams to iPhone to present each buttons' state
• iPhone received UDP datagram
• iPhone handle the data by using RedButtonAPI

How to use all this files?

Make sure you install Arduino IDE and Xcode. And connect Arduino, WiFi Shield, Joystick Shield together.

• Copy & Paste WiShield Folder under your Arduino libraries folder
• Using Arduino IDE to open the file in Arduino/RedButtonAPI/ folder, compile and upload it to your Arduino.
• In Xcode, open SpaceGame.xcodeproj under /iPhone/SpaceGame/ folder, compile and run it on your iPhone.
• On your iPhone's settings, selected WiFi Network named "RedButtonAPI"
• Use the Joystick to control your iPhone game !
