Anti-Snooze Machine

Is it really difficult to wake up from your alarm, does your snooze button seem to always be in reach? Well have no fear this anti-snooze machine has you covered.

Place the touch-sensor on the snooze button, so next time you decide to reach in for the appealing snooze button, the surfer will zoom far from your touch, until you unplug the agent itself.

Parts List

• 2 x 9V Battery 
• Resistors:
• 2 x 220 Ω ± 5%
• 1 MΩ ± 5%
• 2 x photoresistor
• 2 x DC Motor 
• L293D
• Arduino Uno
