This circuit is an Arduino UNO-based automatic liquid hand sanitizer dispenser system. It uses two HC-SR04 ultrasonic sensors to detect the presence of a hand: one sensor controls a 5V mini water pump through a relay for dispensing hand sanitizer, and the other sensor controls a MG996R servo motor for a soap dispenser mechanism. A potentiometer is likely used for adjusting the sensitivity or operational parameters of the system.
