Driving DC motor using Raspberry Pi GPIO , L293D driver and Python.

Driving DC motor using Raspberry Pi GPIO , L293D driver and Python.

Driving DC motor using Raspberry Pi GPIO , L293D driver and Python.

Components required:

1)      Raspberry Pi

2)      L293D IC

3)      Breadboard

4)      DC Motor(s)

5)      Connecting wires

6)      Pi Cobbler, not mandatory though I have used in my circuit.

Connection  

Pi GPIO to L293D to DC Motor.

Pinout diagram of L293D IC 

Connectivity

1	RPi	L293D	Motor
2	GPIO23 (16)	1A(2)
3	GPIO24(18)	1B(7)
4	GPIO25(22)	1E(1)
5		M1A	Terminal 1
6		M1B	Terminal 2
7		+VMotor  to External Source
8	GND	GND

Python program to control the motor

import RPi.GPIO as gpio from time import sleep gpio.setmode(gpio.BOARD) Motor1A = 16 Motor1b = 18 Motor1e = 22 gpio.setup(Motor1A, gpio.OUT) gpio.setup(Motor1b, gpio.OUT) gpio.setup(Motor1e, gpio.OUT) gpio.output(Motor1A, gpio.HIGH) gpio.output(Motor1b, gpio.LOW) gpio.output(Motor1e, gpio.HIGH) sleep(5) # reverse gpio.output(Motor1b, gpio.HIGH) gpio.output(Motor1A, gpio.LOW) sleep(5) gpio.cleanup()
