Then I used their codes, all of them, but none could work.
I confirm that my raspberry pi can work and the connections of lines are correct. And my servo is new so it should work .
Here is my code (It's based on python3):
So what's wrong with my code?
Code: Select all
#! python3 import RPi.GPIO as GPIO import time tilt = 12 GPIO.setmode(GPIO.BOARD) GPIO.setwarnings(False) GPIO.setup(tiltPin, GPIO.OUT) tilt = GPIO.PWM(tiltPin, 50) tilt.start(0) tilt.ChangeDutyCycle(2) time.sleep(1) tilt.ChangeDutyCycle(3) time.sleep(1) tilt.stop() GPIO.cleanup()
