Water Level Indicator Using Arduino in TinkerCad

This article is about a fully functional water level controller using Arduino. The circuit displays the level of water in the tank and switches the motor ON when the water level goes below a predetermined level. The circuit automatically switches the motor OFF when the tank is full. A beep sound is generated when the level in the tank is full.

Step 1: Components You Need:

You will need the following materials for making your own Water Level Indicator:

1. Arduino UNO or nano

2. Breadboard

3. LED's

4. Motor pump

5. Jumper wires

6. Buzzer

7. Resistor (220 ohms)

Step 2: Circuit Diagram:

I have used 4 LEDs for 4 different levels.

1. Green led is connected with pin 2 indicating the level 1 and pump will start automatically at level 1

2. Orange led is connected with pin 3 indicating the level 2

3. Yellow led is connected with pin 4 indicating the level 3

4. Red led is connected with pin 5 indicating the level 4 and buzzer is also connected along with level 4 which means the tank is full.

At level 4 all the 4 less will glow , the buzzer will also beep and the pump will stop automatically
