Then, we simply alternate between GPIO.HIGH and GPIO.LOW every second, inside an infinite loop. Let’s improve the program by making the LED blink indefinitely. Note: in this situation, writing GPIO.output(LED_PIN, GPIO.LOW) was not mandatory because GPIO.cleanup() will do that automatically.

Or even worse, fry your Raspberry Pi (if now you put a push button in GPIO 17 and try to read from it, and the GPIO hasn’t been cleaned up, then you’ll have a problem). It will reset all states and modes for all GPIOs, which can prevent you from having errors in future programs. GPIO.cleanup()Īnd we finish the program by cleaning up the GPIOs, with GPIO.cleanup(). To do that you just have to use one simple command: GPIO.output(), with either GPIO.HIGH to power on the LED, or GPIO.LOW to power off the LED. GPIO.output(LED_PIN, GPIO.HIGH)Īll the setup is finished, we can power on/off the LED. As we want to tell the LED what to do, instead of reading its state, we have to use GPIO.OUT. We need to use the tup() function and provide the mode of the GPIO: either GPIO.OUT for output, or GPIO.IN for input. OK, now we can start setting up the GPIO for the LED. If you don’t set the mode to BCM, then you might end up controlling the wrong pin for your LED.

And the pin number 17 is a 3.3V power pin.

This will allow you to use the GPIO numbers instead of the “standard” pin numbers.įor example, you can see here that GPIO 17 corresponds to pin number 11. This line should be the first line you execute with the RPi.GPIO module.

You will make less mistakes, and in the future if you want to change the LED’s GPIO, you just have to update this variable. This will allow you to use the variable name instead of the number directly. LED_PIN = 17Īs a best practice, we create a “constant” global variable containing the GPIO number for the LED. We also import the time module which we’ll use later to wait for 1 second. You’ll see that this module is quite easy to use. import RPi.GPIO as GPIOįirst we import the RPi.GPIO Python module which will allow us to control all GPIOs from the Raspberry Pi’s GPIO header. Let’s break the program down line by line. This program will power on the LED for one second, and then power it off. Let’s write a minimal program to simply power on and power off the LED. Open Thonny IDE on Raspberry Pi OS (Menu > Programming > Thonny Python IDE) or any other IDE/text editor you like. Now that everything (hardware + software) is correctly setup, you can start to control the LED on Raspberry Pi with Python3. Control the LED with Python 3 on Raspberry Pi OS Then, you can put the micro SD card into your Raspberry Pi and finish the installation with, or without an external monitor. Select “Raspberry Pi OS” as the operating system, and click on “Write” to flash it on your SD card.

Download the Raspberry Pi Imager and plug your micro SD to your computer.

If you haven’t done it yet, first, install Raspberry Pi OS on a micro SD card. This is the 6th pin on the GPIO header, starting from the left, on the inside side.
