Interfacing of Raspberry pi with Motors:

Interfacing of Raspberry pi with Motors:

Now ready to write code to motor.  Turn on your Raspberry Pi and Open the terminal window.

1)   Write a program to Motor move Forward and Backward while switch is pressed.

Create a new text file “motor1.py” by typing the following:

Sudo nano motor1.py

After that write following code to the Text editer page:

import os

import RPi.GPIO as GPIO

from time import sleep

GPIO.setwarnings(False)

GPIO.setmode(GPIO.BOARD) #board usage gpio pin , bcm usasge pin mnumber

GPIO.setup(3,GPIO.IN)

GPIO.setup(4,GPIO.IN)

GPIO.setup(5,GPIO.OUT)

GPIO.setup(6,GPIO.OUT)

print(" interfacing of Switch and Motor")

while True:

    if( GPIO.input(3)== False):

        print("Switch is Pressed then motor move Forward")

            GPIO.output(5,GPIO.HIGH)

            GPIO.output(6,GPIO.LOW)

            sleep(1)

           

    elsif( GPIO.input(4)== False):

       print("Switch is Pressed then motor move Backward")

        GPIO.output(5,GPIO.LOW)

        GPIO.output(6,GPIO.HIGH)

        sleep(2)

       

After writing the code we checked it, save and exit the text editor with

 “Ctrl + x” then “y” then “enter”.

To Running this Code Type:

sudo python motor1.py

then

You will see the Motor moved Forward or Backward when we pressed the switch.

1)   Write a program for Moving Robot.

Create a new text file “motor2.py” by typing the following:

Sudo nano motor2.py

After that write following code to the Text editer page:

import os

import RPi.GPIO as GPIO

from time import sleep

GPIO.setwarnings(False)

GPIO.setmode(GPIO.BOARD) #board usage gpio pin , bcm usasge pin mnumber

GPIO.setup(1,GPIO.IN)

GPIO.setup(2,GPIO.IN)

GPIO.setup(3,GPIO.IN)

GPIO.setup(4,GPIO.IN)

GPIO.setup(5,GPIO.OUT)

GPIO.setup(6,GPIO.OUT)

GPIO.setup(7,GPIO.OUT)

GPIO.setup(8,GPIO.OUT)

print(" interfacing of Switch and Motor")

while True:

    if( GPIO.input(1)== False):

        print("Switch is Pressed then Motor move Forward")

            GPIO.output(5,GPIO.HIGH)

            GPIO.output(6,GPIO.LOW)

            GPIO.output(7,GPIO.HIGH)

            GPIO.output(8,GPIO.LOW)

            sleep(1)

           

    elsif( GPIO.input(2)== False):

       print("Switch is Pressed then Motor move Backward")

        GPIO.output(5,GPIO.LOW)

        GPIO.output(6,GPIO.HIGH)

            GPIO.output(5,GPIO.LOW)

            GPIO.output(6,GPIO.HIGH)

        sleep(2)

        elsif( GPIO.input(3)== False):

       print("Switch is Pressed the Motor move Left")

        GPIO.output(5,GPIO.HIGH)

        GPIO.output(6,GPIO.LOW)

            GPIO.output(5,GPIO.LOW)

            GPIO.output(6,GPIO.LOW)

        sleep(2)

elsif( GPIO.input(4)== False):

       print("Switch is Pressed then Motor move Right")

        GPIO.output(5,GPIO.LOW)

        GPIO.output(6,GPIO.LOW)

            GPIO.output(5,GPIO.HIGH)

            GPIO.output(6,GPIO.LOW)

        sleep(2)

After writing the code we checked it, save and exit the text editor with

 “Ctrl + x” then “y” then “enter”.

To Running this Code Type:

sudo python motor2.py

then

You will see Robot move when switch is pressed.
