“Automatic” Opening Door

For my ENGR-199 class, I was tasked with creating a circuit that would take a user-detected presence, detected through an ultra-sonic sensor, and cause a servo to turn 180 degrees, which would in theory be attached to a door opening system, causing a door to open completely. This effectively creates an automatic door-opening system, which could be utilized in real-world applications. To give a brief background on how the components involved in the circuit work, an ultrasonic sensor sends a...
