DIY Automatic Hand Sanitizer Dispenser 🚰

Hello friends,
Hope you are all doing good. Today, I am showing you how to convert a normal hand sanitizer bottle to an automatic hand sanitizer dispenser machine. This is done using arduino uno, a stepper motor MG 996R and an ultrasonic sensor HC-SR04. The ultrasonic sensor detects the presence of hand near and and triggers a servo motor. The motor arm pushes and dispenses the hand sanitizer.
