The Digital Clock pack includes the MOTHERBOARD and DIGITISER. With these 2 boards you can display values on a seven segment display. The MOTHERBOARD has a built in real time clock module that keeps time even when unplugged. The DIGITISER can display 4 digits or characters and includes 2 buttons and a potentiometer to let you control what’s being displayed, or the brightness of the display. You can display a countdown timer, stop watch, the time, date, or keep score when playing your favourite card or board game. You get to program the MOTHERBOARD, so you decide how your device functions.
