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
Positive Side 10
Negative Side Gnd
 
Programming
 
Arduino Programming
  1. int Fan = 10;      
  2. char mydata = 0;      
  3. void setup()       
  4. {      
  5.     pin Mode(Fan, OUTPUT);      
  6.     Serial begin(9600);      
  7. }      
  8. void loop()      
  9. {      
  10.     my data = int(serial.read());      
  11.     if (y data = = '1') digitalWrite(Fan, HIGH);      
  12.     if (mydata = = '0') digitalWrite(Fan, LOW);     
  13. }   
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
  1. import Serial      
  2. import time      
  3. from tkiner import*      
  4. def Fan_on();      
  5.     arduinoData.write(b '1')      
  6. def Fan_off( );      
  7.     arduinoData.Write(b '0')      
  8. Fan_control_Window=Tk( )      
  9. btn = Button(Fan_control_window,text = "Fan on",command = Fan_on)      
  10. btn2 = Button(Fan_control_window,text = "Fan off",command = Fan_off)      
  11. btn.pack( )      
  12. btn2.pack()      
  13. 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:
  1. Fan_control_Window=Tk( )      
  2. btn = Button(Fan_control_window,text = "Fan on",command = Fan_on)      
  3. btn2 = Button(Fan_control_window,text = "Fan off",command = Fan_off)     
Output
