ThreeDot Electronic Pistol Target

Four Rules Of Gun Safety

  1. All guns are always loaded
  2. Never point a gun at something you are unwilling to destroy
  3. Keep your finger off the trigger until your sights are on the target
  4. Be sure of your target (and what's behind it)


This repo contains an Arduino program to run an electronic pistol target. The target uses simple LEDs, a buzzer, and an Arduino. PCB board layouts can be found in the boards folder. A more detailed write up can be found at

Basically shoot the dot.
