I know I asked this question before, but this time I will give a more clearer description. I have been using the raspberry pi for approximately 6 months now. I am making a very simple robot car that includes a motor and ultrasonic sensor circuit. The ultrasonic sensor works perfectly but the motors aren't spinning with my circuit and programs. Please help:
Info and details:
I am using a 9v battery, and l298n, 2 DC Motors and the raspberry pi and some wires for the motor circuit. You can see the circuit in the picture below made using the app fritzing:
Then I programmed the circuit using the raspberry pi using python and the RPi.GPIO library / module. The code is below:
# importing all modules
import RPi.GPIO as GPIO
import time
GPIO.setmode(GPIO.BOARD)
# Setting up gpio pins for output
GPIO.setup(37, GPIO.OUT)
GPIO.setup(35, GPIO.OUT)
GPIO.setup(33, GPIO.OUT)
GPIO.setup(31, GPIO.OUT)
# Moving the car/ rotating the motor
# This part just moves the car front for 2 secs then back for 2 secs
GPIO.output(37, True)
GPIO.output(33, True)
time.sleep(2)
GPIO.output(37, False)
GPIO.output(33, False)
time.sleep(2)
GPIO.output(35, True)
GPIO.output(31, True)
time.sleep(2)
GPIO.output(35, False)
GPIO.output(31, False)
# Cleaning up
GPIO.cleanup()
There are no errors in the code when I run it (If there are in the code above, then that's probably true because I didn't copy and paste the code, I just wrote it here, so there might be a typo or something). The program just doesn't do anything. I ran it on idle in the raspberry pi. Please help, any good help will be useful thank you! Thank you as it means a lot!!
