Controlling Fan Using Arduino

Introduction

In this article, I am going to explain how to control a fan by using two buttons, using Arduino. Arduino will be used to control the fan by clicking the button.

 

Parts Lists

 

Hardware Parts

• Arduino Uno
• Fan
• Bread Broad
• HookUp Wires 

Software Parts

• Arduino IDE
• Python IDLE 

Connection

Connecting the fan to the Arduino Board is simple. Given below are the instructions for connecting the fan.

Fan	Board
Postive Side	10
Negative Side	Gnd

Programming

Arduino Programming

int Fan = 10;
char mydata = 0;
voidsetup()
{
    pin Mode(Fan, OUTPUT);
    Serial begin(9600);
}
void loop()
{
    my data = int(serial.read());
    if (y data = = '1') digitalWrite(Fan, HIGH);
    if (mydata = = '0') digitalWrite(Fan, LOW);
}

In the Arduino Side, run the above program. If we set 1, it will be high and if we set 0, it will be low.

 

Python Programming

import Serial
import time
from tkiner import*
def Fan_on();
arduinoData.write(b '1')
def Fan_off( );
arduinoData.Write(b '0')
Fan_control_Window=Tk( )
btn = Button(Fan_control_window,text = "Fan on",command = Fan_on)
btn2 = Button(Fan_control_window,text = "Fan off",command = Fan_off)
btn.pack( )
btn2.pack()
arduinoData= Serial.Serial("COM4",9600)

Explanation

In Python, the above program is used to connect the Serial monitor with the Board. For creating the ON and OFF buttons in Python, the following code will be used:

Fan_control_Window=Tk( )
btn = Button(Fan_control_window,text = "Fan on",command = Fan_on)
btn2 = Button(Fan_control_window,text = "Fan off",command = Fan_off)

Output
