Hi Guys

I am totally newbie and am learning Robotics for the first times I brought L298N motor controller board looking at the GPIO TinkerBoard Wiki page GPIO I have connected my wires as such

from L298N GND goes into Asus Tinker board pin 39

for Motor1 the pin goes to 37/38
for Motor2 the pint goes to 35/36

when I turn the Board on the motors starts spinning first the left side then the right side , when I run my code it executes and then goes back to its spining

here is my code :

  import sys
  import time
  import ASUS.GPIO as GPIO

  mode=GPIO.getmode()

  GPIO.cleanup()

  m1 = 38 #forward is working
  m2 = 36
  sleeptime=1

  #GPIO.setmode(GPIO.BCM)
GPIO.setmode(GPIO.BOARD)
  GPIO.setup(m1, GPIO.OUT)
  GPIO.setup(m2, GPIO.OUT)

  def forward(x):
GPIO.output(m1, GPIO.HIGH)
print("Moving Forward")
time.sleep(x)
GPIO.output(m1, GPIO.LOW)

  def reverse(x):
GPIO.output(m2, GPIO.HIGH)
print("Moving Backward")
time.sleep(x)
GPIO.output(m2, GPIO.LOW)

  for x in xrange(1,2):
forward(2);
reverse(1);

  GPIO.cleanup()

Any help would be very much appericated

Does anyone have any ideas on how to fix this ?

Hi,

Could you draw your wiring diagram for us?
And what is the model of your L298N control board?
(maybe take a photo)

Because it looks like missed a lots of parts code.

e.g.

Quote:missed 37 define
missed 35 define

which L298N GND connect to pin 39?
and where is the power source?

code example:

Code:
pin1 = 37;

pin2 = 38;

pin3 = 35;

pin4 = 36;

GPIO.setup(pin1, GPIO.OUT)

GPIO.setup(pin2, GPIO.OUT)

GPIO.setup(pin3, GPIO.OUT)

GPIO.setup(pin4, GPIO.OUT)

# m1

def m1_forward():

GPIO.output(pin1, GPIO.LOW)

GPIO.output(pin2, GPIO.HIGH)

def m1_reverse():

GPIO.output(pin1, GPIO.LOW)

GPIO.output(pin2, GPIO.HIGH)

# m2

def m2_forward():

GPIO.output(pin3, GPIO.LOW)

GPIO.output(pin4, GPIO.HIGH)

def m2_reverse():

GPIO.output(pin3, GPIO.LOW)

GPIO.output(pin4, GPIO.HIGH)
