Using Firmata

What is Firmata?

Firmata is a protocol for communicating with microcontrollers (like Arduino) from software on a computer, using a standardized messaging format over serial communication (usually USB). It allows you to control and read from Arduino pins in real-time, without needing to constantly upload new Arduino sketches.

  • Firmata is like a translator that is programmed on the Arduino.

  • You upload a Firmata sketch once to the Arduino.

  • Then, you can control the Arduino live from TouchDesigner (or other software like Isadora, Max/MSP or Processing) without reprogramming it.

  • Be aware that is is resource heavier the programming your Arduino with specific code for the goal you want to achieve, Nice for prototyping though!
