When I connect everything right and run a simple program, only thing I see is a very low buzzing sound from motor while program running. Is my battery too low to move motor?
The code :
import RPi.GPIO as GPIO from time import sleep GPIO.setmode(GPIO.BOARD) Motor1A = 38 Motor1B = 40 Motor1E = 7 GPIO.setup(Motor1A,GPIO.OUT) GPIO.setup(Motor1B,GPIO.OUT) GPIO.setup(Motor1E,GPIO.OUT) print "Going forwards" GPIO.output(Motor1A,GPIO.HIGH) GPIO.output(Motor1B,GPIO.LOW) GPIO.output(Motor1E,GPIO.HIGH) sleep(2) print "Going backwards" GPIO.output(Motor1A,GPIO.LOW) GPIO.output(Motor1B,GPIO.HIGH) GPIO.output(Motor1E,GPIO.HIGH) sleep(2) print "Now stop" GPIO.output(Motor1E,GPIO.LOW) GPIO.cleanup()

I used Raspberry pi's 7(motor 2 enable),38(IN4),40(IN3)pins.
