Supplies

Step 1: Code

You can find the code on Github.

Upload this code to the Arduino.

Step 2: 3D Print

You can find/edit the model here.

Step 3: Put in the Arduino Micro

Step 4: (optional) Screw the Arduino Micro to the Base

  • 4x M1.4x4 screws

Step 5: Connect the Buzzer

  • 1x Buzzer (CEET120B085)
  • 6x Jumper shunts
