ToyBomb
great for young sappers
Support pesetting of time by 3 keys on the shield, shows remaining time, beeps, blinks, all wires have special effects when being disconnected, cutting only 1 of 4 wires will stop the countdown ... Good luck!
Hardware:
- Arduino UNO
- arduino-multi-function-shield (see photo)
- 4x2 wires (must connect 4 pins of the shield to GND for normal operation, see photo)
