To measure the level of water using an Ultrasonic sensor.
Description:
Ultrasonic sensors work by emitting sound waves at a frequency too high for humans to hear. They then wait for the sound to be reflected back, calculating the distance based on the time required.
Hardware Requirements:
Arduino UNO
Ultrasonic sensor HC-SR04
330 Ohm resistor
Breadboard
Jumper wires
LED (Green / Red)
