Story

This is a little bit hard project. But I will explain it in a simple manner.

How It Works ?

The Arduino turns the water pump ON/OFF by calculating the data received from the Ultrasonic Distance Sensor. If the data is a particular distance (In Code - Inches) less from the sensor, then the Arduino turns the water pump ON. After turning it ON, it checks if the data is a particular distance (In Code - Inches) high from the sensor, the the Arduino turns the water pump OFF.

How I made this project

I was worried about the overflow of the water from my water tank. I loses a huge amount of water from it. So, I started thinking of a way to get rid of it. I came with an idea of making a system which controls the water pump.

I started to think practically and wrote the code logically. But, I came with a bad news - "NOT WORKING PROPERLY".

Then I took my phone and started searching for one like this. After a while of searching, I got the article. It was from You Tube. This is not my project. It is owned by : Kiyani's Lab

His video gave me the code for this project.

Components Required :-

Arduino Uno

16 x 2 LCD Display

Ultrasonic Sensor (HCSR-04)

Breadboard

Potentiometer (10k)

Jumper Wires (Female - Male)

1k Resistor

Relay Module

Push Button

SPST Switch

Circuit DIagram

CIRCUIT DIAGRAM

Do the wiring as shown in the Circuit Diagram

Here it is Arduino Nano.

You can use any of the Arduino Boards.

Ultrasonic Sensor To Arduino Uno :-

Ultrasonic Sensor gnd(Ground/Cathode) to Arduino Uno's gnd pin. Its Vcc pin (5v/Anode) to Arduino Uno's 5v pin.

Its Trig(Input) pin to Arduino Uno's D8 pin and Echo(Output) pin to Arduino Uno's D9 pin.

LCD Screen To Arduino Uno :-

16 x 2 LCD Display Pinout Diagram

VSS - GND

VCC - 5v

VEE/VO - Potentiometer Wiper Pin (Centre Pin). Potentiometer other two end pins to - One to Arduino Uno's 5v and and other to its Gnd

RS - D2

RW - Gnd

E - D3

D0 - Gnd/No Connection

D1 - Gnd/No Connection

D2 - Gnd/No Connection

D3 - Gnd/No Connection

We are not connecting LCD Screen's (D0, D1, D2, D3) pins because we are using 4 bit mode to display the text.

D4 - D4 (Arduino Uno/Nano/Mega/Any Other Board)

D5 - D5 (Arduino Uno/Nano/Mega/Any Other Board)

D6 - D6 (Arduino Uno/Nano/Mega/Any Other Board)

D7 - D7 (Arduino Uno/Nano/Mega/Any Other Board)

Led Anode [ Short Form - A] / (LED +) - 5v (Arduino Uno)

NOTE: Use a resistor while connecting (I used 1k). Otherwise the led may burn due to high voltage ⚠.

Led Cathode [Short Form - K] / (LED -) - Gnd (Arduino Uno)

RelayToArduinoUno:-

Connect Relay modules IN (Signal/INPUT) to Arduino Uno's D12 pin.

Relay's Gnd to Arduino Gnd. Its 5v pin to Arduino's 5v

MODE(AUTO/MANUAL)SwitchToArduino:-

Connect the switch's one end to Gnd of Arduino and the other end to D11 of Arduino Uno.

PUMP(ON/OFF|DISTANCESET)SwitchToArduino:-

Connect the push button switch's one end to Gnd of Arduino and the other to its D10 pin.
