About this product
A two-player chess clock project with two TM1637 4-digit displays. Each player has five minutes on their own display, and pressing a player button stops that clock and starts the opponent's. A buzzer sounds when a player's time runs out. The project uses millis() for timing and teaches state switching between players. This expansion version excludes the Arduino board and USB cable.

Frequently asked questions
Do I need an Arduino board for the chess clock expansion kit?
Yes. The expansion version does not include an Arduino board or USB cable. Use an Arduino Uno or a compatible board to run the code and drive the two TM1637 displays.
Why does the clock use two TM1637 displays?
Each TM1637 shows the remaining time for one player, so both players can read their own clock. The two displays are wired to the Arduino separately, with each one using its own clock and data pins.
