GPIO.output (x, False) Doesn't work

syedzainnasir 07 Mar 2017 RaspberryPi Projects Forum

I need help troubleshooting this. I am trying to get my relay working using a very simple Python codes. Here it is:

[code]import RPi.GPIO as GPIO
GPIO.setwarnings(False)
GPIO.setmode(GPIO.BOARD) 
GPIO.setup(37, GPIO.OUT)
import time
for x in range (0,3):
   GPIO.output(37, True)
   print "Lights on"
   time.sleep(3)
   GPIO.output(37, False)     <<<here where it is supposed to turn off but doesn't
   print "Lights off"
GPIO.cleanup()    <<< Relay's green light turn off here[/code]
