A set for building a simple electronic watch worn on a wrist. It was based on the popular ATmega328 microcontroller with Arduino bootloader. The watch is powered by a CR2032 coin cell battery, which allows the device to operate for up to 2 years. The electronic board is placed in a nice acrylic casing, and the watch is attached to the wrist with an adjustable strap. The default software shows the time on a 4-digit 7-segment display when the button is pressed. There is a connector on the side of the board, through which the user can reprogram the microcontroller and add his own functions.
