To program the Edison to control and interact with the Arduino, you’ll need

to use the UART to establish a communication protocol between the

devices. See the next section for an easy example of UART communication

between Arduino and Edison.

Controlling the Arduino Block with

Firmata

Firmata is an established protocol popular within the Arduino realm for

applications that require a separate machine (usually a computer) to control

the Arduino. It’s a serial-based protocol that uses defined messages to set

digital pins, read analog pins, and do everything else you’re used to with

Arduino.

Firmata is so useful, the standard Arduino IDE even ships with the Firmata

library. Here’s an example of how an Edison can be used to control and

interact with an Arduino running Firmata.

Upload StandardFirmata to the Arduino

Before uploading any code to the Edison, let’s load something into the

Arduino. Once the Firmata code is running on your Arduino, you may never

have to upload code to it again.

Using the standard Arduino IDE (i.e. not the IDE built for Edison), load up

the “StandardFirmata” sketch by going to File > Examples > Firmata >

StandardFirmata. If you have the Codebender addon installed, you can

use the embed below to upload the code to your Arduino Block.

With the Firmata firmware uploaded, you can disconnect the FTDI Basic,

and connect the Arduino Block to your Edison stack.
