TAP Game - My DIY Reaction Game

This is TAP Game — my fully homemade pocket-sized two-player reaction game.

How to play:

Central SIGNAL LED blinks 3 times — get ready!

After a random delay the signal lights up

First player to smash their big tactile button wins the round

Each player has 3 heart LEDs for score tracking

First to 3 points wins the match

It runs on a single CR2032 coin cell using a bare ATmega328P (internal 8 MHz). Fully custom KiCad PCB, hand-soldered SMD components. Super compact and makes an excellent keychain for your keys!
