Tofu Piano with Arduino

Finally, a good excuse to play with your food.
Join us as we show you how to make use of capacitive sensing to turn regular blocks of tofu into "piano keys" that trigger different notes to be played on an Arduino.


No prior experience necessary. We'll guide you along as you put together the code and circuit. Suitable for anyone aged 8 to 18. We offer differentiated tracks so more advanced participants don't get bored and newbies don't get lost.

Here's what you get

  • 2 hours of fun!
  • Wires
  • Resistors
  • Tofu (actually tau kwa, but "tofu" sounds nicer)
  • Passive buzzer

What to bring

  • Laptop, preferably with the following free software installed:
    • Arduino IDE (Windows, Mac)
    • [OPTIONAL] Our custom version of Scratch for Arduino (S4A), if you'd like a gentler introduction to programming. (Windows, Mac)
  • Arduino or compatible, with USB cable
  • breadboard

If you don't already have your own Arduino and breadboard, you can purchase them from us together with your ticket. We don't carry the official Arduino, but prefer the Freaduino UNO which has additional features that make it more useful for beginners and hobbyists. The breadboard we carry is a transparent full-sized breadboard that not only looks good, but also helps beginners see what's going on inside
