A guitar is a plucked stringed musical instrument. Normally, the guitar is an expensive instrument, but here we create a cheap and convenient DIY instrument that can help you enjoy and play real chords on an electric micro:bit guitar. Have fun and enjoy playing the micro:bit guitar by shifting the pitch up and down octaves.

How it Works?

When you touch pin 1 or pin 2 and GND it will play a broken chord, but now you can move the chord down an octave (lowering its pitch) by pressing button A and move it up an octave (raising its pitch) by pressing button B.

The pitch (frequency) of a note doubles when you move up one octave: middle A has a frequency of 440Hz (440 vibrations per second), high A has a frequency of 880Hz. This is why making the vibrating part of guitar strings different lengths with your fingers changes the pitch of the note being played.

Materials you need

  • micro:bit and optional battery pack
  • 4 crocodile clip leads
  • cardboard, scissors, glue, tin foil
  • headphones, buzzer, or powered speaker

How to build and play your electric guitar

You can connect the electric guitar to some headphones with some crocodile clips you attach to the phone jack.
