Water Level Detection System

This project is a water level detection system using an HC-SR04 ultrasonic sensor and Arduino Uno. The ultrasonic sensor functions to measure the distance between the sensor and the water surface. This distance data is then processed by Arduino to determine the water level. Two LEDs are used as indicators: a red LED will light up if the water level exceeds a certain limit, while a yellow LED will light up if the water level is within a safe limit. This circuit consists of several main components: an HC-SR04 ultrasonic sensor, an Arduino Uno, two LEDs (red and yellow), and several resistors to limit the current to the LEDs. This system is very relevant for applications monitoring water levels in tanks or other containers.
