pi red light blinking code example
Example: blinking an led with raspberry pi
import RPi.GPIO as GPIO # IMPORTANT: remember to change the gpio pin (18) also it needs to be programmed in Thonny Python IDE
import time #used in raspberry pi model 4
GPIO.setwarnings(False) #NOTE: raspberry pi could be updated, and you might need to change your code
GPIO.setmode(GPIO.BCM)
GPIO.setup(18, GPIO.OUT)
while True:
GPIO.output(18, True)
time.sleep(1)
GPIO.output(18, False)
time.sleep(1)
