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!
Make a robot friend with Adafruit’s CRICKIT – A Creative Robotics & Interactive Construction Kit. It’s an add-on to our popular Circuit Playground Express, FEATHER and other platforms to make and program robots with CircuitPython, MakeCode, and Arduino. Start controlling motors, servos, solenoids. You also get signal pins, capacitive touch sensors, a NeoPixel driver and amplified speaker output. It complements & extends your boards so you can still use all the goodies on the microcontroller, now you have a robotics playground as well.
