Learn to use thread - tony1812 - Jul-29-2017
Hello, I am experiment with thread on the Pi. I want to keep the main thread for the UI. Start a new threat to turn a relay on and off. The part for the relay tread is:
import threading, time
#from tkinter import *
from time import sleep
#Prepare GPIO
import RPi.GPIO as GPIO
GPIO.setmode(GPIO.BOARD)
GPIO.setwarnings(False) #disable annoying warning messages
GPIO.setup(40,GPIO.OUT)
#initially is off
GPIO.output(40,GPIO.LOW)
def foo():
print ("Hello threading!")
def timed_on_off():
GPIO.output(40,GPIO.HIGH)
sleep(4)
GPIO.output()
sleep(4)
my_thread = threading.Thread(target = timed_on_off)When I run it in Thonny, it doean't give me any error but neighter functions foo() nor timed_on_off() does anything. What am I doing wrong ? Thanks.

You should start your thread:
my_thread.start()
