Interaction is the bread-and-butter of countless memorable projects, installations, and even games. Be it scrolling your way through history or playing plants as musical instruments, Arduino Uno’s are a one-stop-shop for DIY brilliance and clever interaction, often requiring only a bit of coding and some hardware. The Arduino Uno, legendary among microcontrollers for its ease-of-use, can make even the smallest electric signals create spectacular products. An Arduino is also a great way to extend your TouchDesigner knowledge beyond the screen. If you can think it, you can make it with an Arduino and a bit of elbow grease!
Making the Most of Microcontrollers
Microcontrollers are tiny computers capable of running (often) low-level computation, processing periphery input, and typically outputting data to another processor. In English, this time — microcontrollers are little computers you can use to take an electric signal — say, a slider moving up and down — translate it into data, and ship that data off to be used by much bigger computers.
A typical microcontroller converts real-world electricity into digital values usable by computers with very little additional user input. Some require soldering to install, but many are tailored towards beginner-friendly, solderless applications needing only some knowledge of how electric signal flow works.
Arduino Uno?
An Arduino is a microcontroller made to be versatile and easy-to-implement. The Arduino Uno is rather cheap and extremely powerful, capable of converting up to 5 analog signals into digital values, outputting in real-time with very little latency. Moreover, the Arduino Uno is built around the breadboard paradigm — rather than have to solder your connections by hand, you can use small conductive plates called “breadboards” to create complex circuits with only a few small wires.
Arduino Uno’s plays very, very nicely with TouchDesigner, extending the digital platform far into the physical and back again. They can be sourced just about anywhere in the world and you can often buy full prototyping kits full of sensors, actuators, and LEDs for less than $100. We’ll be taking a look at how some artists have used Arduino and TouchDesigner for their work, from tiny to massive, below!
Some Arduino & TouchDesigner examples
The Perfect Arduino Portfolio
P. G. Lucio’s knowledge is a boon: here, he’s filled a webpage with experiments connecting Arduino to TouchDesigner, from ultrasonic-sensitive particles to pixel sorting algorithms. A masterclass in connectivity between TouchDesigner and microcontrollers! The header image of this post is also from Pablo’s behance below:

Water, Water Everywhere
Arduino supports nearly any niche sensors you can get your hands on — if it outputs electricity up to 5 volts, you can use it as a control source for anything!
