An Automatic Door Sytem prototype that uses an Ultrasonic sensor and a Servo motor otherwise known as SG90
The project involves coming up with a proof-of-concept automatic door system that helps reduce coming into contact with contaminated surfaces, e.g. a door in a public place, most especially during this day and age of Covid-19. The door is automated in such a way that it opens once one comes within range of the Ultrasonic sensor.
