Adabot needs your help, Doctor! It's time to operate!! It takes a steady hand to remove the game pieces!

You can build this fun, classic game using a Circuit Playground Express to react whenever your hand isn't so steady and your tweezers bump the edge of an opening. You'll build the board, and then program the Circuit Playground Express using CircuitPython or MakeCode to test the capacitive touch pads for contact.

A tip of the hat goes to Maker Camp for their inspiring project using the Makey Makey board.


To build this project you'll need the parts below, as well as a computer for programming and uploading code to the Circuit Playground Express.

1 x Circuit Playground Express
Round, Awesome Microcontroller Board
1 x Copper Foil Tape
25mm x 15 meter roll
1 x 3x AAA Battery Holder
with On/Off Switch and 2-Pin JST
1 x USB Cable
A/MicroB - 3ft

Materials & Tools

In addition to the parts listed above, you'll also need:

  • Small cardboard box, such as an Adafruit shipping box
  • Metal tweezers
  • Color printer with white paper or cardstock
  • Hobby knife or scissors
  • Glue stick
  • Scotch tape
  • Small Philips screwdriver
