Revisiting Basics
Using a Raspberry Pi 4 A blinking LED is the Hello World for physical computing. Raspberry OS allows many ways to do this. Here are 3 ways to Blink an LED from the RPi 4. Figure 1: Blinking LED wiring on RPi 4 (from Tutorial 3 below) (gpiozero) Blinking LED Raspberry Pi Tutorial 1 This tutorial is great not just for blinking LED but also intro to "Physical Computing": Getting started with Breadboard. Resistor labeling code diagram included. Using a multimeter to test power provided by the RPi Understanding basic circuit first not controlled, then controlled by the RPi. Using Python from a command window, testing basics 1 line at a time. Intro to import gpiozero , a pre-installed on RPi library with import for basic needs like LEDs and buttons. from gpiozero import LED import time led = LED(17) # GPIO17 led.on while True: led.toggle() time.sleep(1) (GPIO) Bl in king LED Raspberry Pi Tutorial 2 Alte...
