A more accessible fridge

Problem: Fridges alert users when their fridge door is open by beeping loudly. For users who are hard of hearing, this is not a feasible indicator.

Solution: Fridge flashes a bright light to get the attention of the user to notify them that their fridge door is open

Proof of Concept: Using a ultrasound sensor, an LED and a SparkFun, I created a simple state machine. If the ultrasound sensor is sensing a distance of more than 20 centimeters it begins flashing the LED. Otherwise, the LED remains off.
