Musical Hands

A Theremin is a type of early electrical instrument that creates sound based on the position of the user’s hands. For our Little Robot Friend trick, we’re using the builtin motion sensor, the accelerometer, to get input in order to make different sounds.


Using the Trick

Here’s how to use this trick:

  • Download the code.
  • Upload the code using the Arduino IDE.
  • Tilt your bot back and forth to hear the difference in pitch.
  • Tap the bot’s hair sensor to turn the sound on or off.
