Circuit Documentation

Summary

This circuit consists of an Arduino UNO microcontroller interfaced with a Water Level Sensor and a Servo motor. The Arduino UNO is responsible for reading the water level from the sensor and controlling the position of the Servo based on the sensor's readings. The Water Level Sensor is powered by the 5V output from the Arduino and sends its signal to one of the Arduino's analog inputs. The Servo is controlled by a digital output from the Arduino and is also powered by the 5V supply.

Component List
