T3 Lesson 6: Node-Red and programming the GPIO pins

Note:  This is divided into two section

INTRODUCTION

Slides

This lesson introduces Node-Red and how it can be used to control the GPIO pins on the Raspberry Pi.   The first part of the lesson is seeing how Node-Red is a programing language that follows the basic concepts identified earlier.  The second part is in understanding the GPIO pins and how they function with and without Node-Red. A challenge activity that students build such as push button timer or stop lights will be available soon.

APPLICATION

Here are three tutorials that you can explore with your students that all go over basic Node Red GPIO pin functions.

RPi Node-Red: RGB LED

 

RPi Node-Red: Push Button

RPi Node-Red: Buzzer
