Arduino OSC step by step howto

This tutorial provide step by step that help you to  setup a OSC ready Arduino which allows you to send instruction to your Arduino wirelessly from your iOS/Android device by using TouchOSC

You need the following component to construct your setup

1. Arduino board (Mega 2560, UNO…etc)

2. Arduino compatible Ethernet Shield

3. Low power consumption servo unit, recommend a mini or micro sized servo.

4. Power supply, for example 5v, 2A

5. Wireless AP/Router, DHCP enabled.

Software :

// Receive from iOSC http://recotana.com/iphone/iosc/en/index.html and apply to arduino pins via OSC .
