Mini Project Automatic Water Dispenser using Arduino

The Automatic Water Dispenser concept is really basic. We will utilise an HCSR04 Ultrasonic Sensor to determine whether any object, such as a glass, is put in front of the dispenser. A solenoid valve will be used to control the flow of water; when activated, water will flow out, and when deactivated, water will stop. So we’ll develop an Arduino programme that checks to see if any object is placed near the tap; if so, the solenoid will turn on and wait until the thing is removed; once the object is withdrawn, the solenoid will switch off automatically, cutting off the water supply.
