Summary of the Circuit

This circuit is designed to interface an Arduino UNO with a servo motor and a water level sensor. The Arduino UNO acts as the central processing unit, controlling the servo motor based on the input from the water level sensor. The servo is powered by the 5V output from the Arduino and receives pulse-width modulation (PWM) signals to control its position. The water level sensor provides a signal to the Arduino, which can be used to determine the water level and subsequently control the servo motor.

Component List
