Summary

This circuit is designed to monitor water levels using a water level sensor and provide feedback through a buzzer and an LED. The system is controlled by an Arduino UNO microcontroller, which processes the sensor data and activates the buzzer and LED accordingly.

Component List

1. Water Level Sensor

   • Pins: SIG, VCC, GND
   • Description: Measures the water level and outputs an analog signal.
   • Purpose in Circuit: Provides water level data to the Arduino.

2. Buzzer

   • Pins: PIN, GND
   • Description: Emits sound when activated.
   • Purpose in Circuit: Provides audible feedback when certain water levels are detected.

3. LED: Two Pin (red)

   • Pins: Cathode, Anode
   • Description: Emits red light when powered.
   • Purpose in Circuit: Provides visual feedback when certain water levels are detected.

4. Arduino UNO

   • Pins: UNUSED, IOREF, Reset, 3.3V, 5V, GND, Vin, A0, A1, A2, A3, A4, A5, SCL, SDA, AREF, D13, D12, D11, D10, D9, D8, D7, D6, D5, D4, D3, D2, D1, D0
   • Description: Microcontroller board based on the ATmega328P.
   • Purpose in Circuit: Controls the entire system, processes sensor data, and drives the buzzer and LED.
