Raspberry Pi Smart Display Module · File : gpio-led-blink-python.py · Language : Python · Use case : Allumer et éteindre une LED connectée aux GPIO pour tester la sortie numérique.

Simple script using RPi.GPIO library to control an LED via a digital output.

Requires a Raspberry Pi Smart Display Module with Compute Module 5. Connect an LED with a 220Ω resistor between GPIO pin 17 and ground. Ensure the RPi.GPIO library is installed via pip. Run the script with sudo python3 script.py for GPIO permissions.

        GPIO.output(LED_PIN, GPIO.LOW)   # Éteindre
