Firmata - Arduino (part 1)

Introduction

First step is installation Firmata library on Arduino shield. Installed library allows to use Arduino as the A/D and D/A. The control logic will be on Raspberry and communicate will be over USB (Firmata protocol) with Arduino.

We need

• Arduino board (in my example is it ArduinoMega)
• Arduino IDE Software
• PC with USB port ;)

ArduinoMega board

Arduino IDE Software

Download and install Arduino IDE from page http://arduino.cc/en/Main/Software

Connect Arduino to PC and run Arduino IDE:

# sudo ./arduino

If you use linux, you need to use root (sudo) access to have access to the USB port.

select valid Arduino port:

select valid Arduino board:

select Standard Firmata library:

compile and send library to Arduino board:

It's all. Arduino is ready.

We can't test without a second module - Raspberry. How to connect with Rasspbery I will explain in the next post.
