Arduino Firmata implementation for Unity: 'Object-Oriented Arduino'

Arduino

• Upload Standard Firmata (included with Arduino) to your board and use Unity with sensors and actuators.

• Find the name (OSX) or number (Windows) of the Serialport under Tools/Port. Remember the numeric part at the end. You need to add this in the Unity script.

Unity (tested in Unity 5.6.1)

• Make a new project or use the project you are currently working in.
• Go to Assets > Import Package ...
• Select the OOArduino.unitypackage
• Import.

After import you'll probably see a lot of red warning signs in the console.

Like: error CS0234: The type or namespace name 'Ports' does not exist in the namespace 'System.IO'
Thats because you have to configure the 'Api Compatibility Level' to '.NET 2.0'. To do that:

• Go to File > Build Settings ...
• Then Player Settings (it opens in the Inspector at the right side).
• Click 'Other Settings'
• You can find 'Api Compatibility Level' under Configuration
• Select '.NET 2.0' (by default it's '.NET 2.0 Subset')

And the errors will disappear.

• Then Select the Main Camera (actually you can attach a script to something else as well) in the Hierarchy.
• Add Component (inspector)
• Scripts > OOArduino > Arduino Controller
• Press play
• Now you probaly see a log that says 'Started'

ArduinoController: Doing something with Inputs and Outputs

• ArduinoController.cs is the script you need to modify.
• Modify the constants (like LED1_PIN == 05) to your own needs.
• Change the pinConfiguration array to make it fit your own Arduino configuration.
• Do all the writing / reading of the pins within the if( arduino.IsConnected() ) statement.
