UPDATE Issue only happens when load is connected, triggers every time without load
As the title mentions, it works fine until I try to switch it off the second time round, then I see the red LED turning on (it looks a touch dim).
Tapping the relay housing(lightly) triggers the relay Stuck relay then!
But why only after the second attempt and never on the first power off ?
EDIT: I looked at the datasheet thinking it needs a bit more voltage, but max is 3.9v!
import RPi.GPIO as GPIO #from time import sleep pin =2 # Set up input pin # set bcm pin mode GPIO.setwarnings(False) GPIO.setmode(GPIO.BCM) GPIO.setup(pin, GPIO.OUT) # turn on relay in revese mode so sety pin to low state = GPIO.input(pin) if state: print('on') GPIO.output(pin, GPIO.LOW) else: print('off') GPIO.output(pin, GPIO.HIGH)
I have posted this on the raspberry pi.stackexchange but think the question may be better suited here. Thank-you.
