TouchDesigner & Arduino

You can use Arduino to send (sensor) data to TouchDesigner and vice versa.

For example, you might want to measure the light condition of a room and use this data to trigger something in TouchDesigner. Or you might want to be able to have a light bulb react to a sound file, or a motor spin in sync with a projection.

Using Serial Communication

Serial communication is a method for transferring data between devices. It is able to send data sequentially over a wire. In this case the USB cable that connects your Arduino with the computer running TouchDesigner.
