Hey everyone! Steve Perry here.
Do you like DIY projects? If so, make sure to check out my IoT Smart Home series at IBM developerWorks.
It is made up of three installments, which guide you through a DIY smart home project from start to finish.
Part 1 – Setup the hardware
In Part 1 I give you an overview of the project, including a complete parts list, and three videos that show you how to setup your Raspberry Pi 3, give you a quick tutorial of how to use a solderless breadboard, and how to setup the 433MHz receiver and transmitter modules on the breadboard.
Part 2 – Setup the software
In Part 2 I show you how to download, build, and use the software you’ll need to run on your Raspberry Pi to communicate with the Raspberry Pi, called WiringPi, and 433Utils, how to use the WiringPi gpio utility, and show you how to capture the 433MHz encoding signals sent from the IoT device remote controls using a program you’ll build from 433Utils called RFSniffer.
Part 3 – Control the smart home
In Part 3 I show you how to setup your Watson IoT platform app that acts as the MQTT broker, how to build, test, and run the software that runs on the Raspberry Pi to control the smart home devices, and how to build and run the Android app that controls the system from your mobile phone.
Oh, there will be videos
Each part of the tutorial has three videos to let you see what I did to build the project, to help deepen your understanding of the technology, and to give you a jump start when you build the project for yourself.
In future posts, I’ll expand on each of these. I’m excited, and I hope you are too.
Get started with Part 1
To get started, check out Part 1, and order your parts. The entire project costs about 125USD, including the Raspberry Pi 3, and a 16GB micro SD flash drive. Not bad, IMO.
If you already have a Raspberry Pi 3 and 16GB (or larger) micro SD card, and want to get started, check out the video below, where I show you how to download and flash the Raspbian Stretch image onto the micro SD card and setup your Pi.
Thanks for reading!
