In this project, I will show you how to start designing and coding for home automation using Node-RED on the Raspberry Pi. I will be using a Pi Zero W, and an Arduino Uno.
First off, you need to set up your Raspberry Pi and make sure it is running. There are lots of tutorials online on how to do that so I won’t explain that as it is quite straightforward.
Once you are in the Raspian OS, you need to click the Node-RED app, which will take you to a terminal window.
If you want to set up some security for your code, check this project out!
Now, with everything installed, it’s time to start doing actual work. Get to a computer and find out your Raspberry Pi IP address (your Pi should be connected to internet) and the address should look something like this: 192.168.0.105. After finding it out, type it in a web browser, adding “:1880” at the end. A Node-RED page should appear.
Each Friday is PiDay here at Adafruit! Be sure to check out our posts, tutorials and new Raspberry Pi related products. Adafruit has the largest and best selection of Raspberry Pi accessories and all the code & tutorials to get you up and running in no time!
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, or even use Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for MakeCode, CircuitPython, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
