| + | Using the open source software OpenHAB, we’ll be building a Raspberry Pi touchscreen command center that can interface with over 150 different “smart home” products, and provide an interface for control and task scheduling. Instead of using an existing product though, we’ll build our own WiFi enabled RGB LED strip that interfaces with OpenHAB, allowing you to wirelessly control it from your smartphone or any computer on your network. | ||

| + | OpenHAB is great because it interfaces with so many products, it’s free, it’s open source, and extremely flexible. It also runs on Windows, OS X, and Linux, so you don’t necessarily have to use a Raspberry Pi for this project. If you have an old laptop or desktop kicking around, you can just as easily run the same setup. | ||

| + | The main parts for this build are a Raspberry Pi and touchscreen, | ||
| + | |||
| + | ==== Step #1: Assemble the Raspberry Pi and touchscreen ==== | ||
| + | {{: | ||
| + | * Without instructions, | ||
| + | * Start with the screen face down and flip the display controller board over so that the large connector is visible. Connect the large ribbon cable from the screen to the controller, being sure to push the cable in fully and securing it with the clip on the connector. | ||
| + | * Flip the display controller board onto the back of the screen, and push the small touchscreen cable into its connector. Screw the standoffs into the back of the screen, through the holes in the controller board. | ||
| + | * Insert the ribbon cable into the display connector on the side of the controller board, then place the Pi on top of the standoffs and screw it in. Connect the other end of the ribbon cable to the display connector on the Pi. | ||
| + | * In order to run power and ground to the touchscreen, | ||
| + | ==== Step #2: Setup the microSD card and configure Raspbian ==== | ||
| + | {{: | ||
| + | * Download the latest build of Raspbian from the Raspberry Pi website and flash it onto a microSD card. Then insert the card into the Pi. | ||
| + | * Plug in a keyboard, mouse, and wifi adaptor, then insert the card into the Pi and boot it up. | ||
| + | * Go through the configuration process, and when it's fully booted, connect to your WiFi network. | ||
| + | * In order to get the touchscreen to work, you’ll likely need to run a few commands from the command line to update Raspbian: sudo apt-get update sudo apt-get upgrade This will probably take a while, so be patient! | ||
| + | * If you restart the Pi after the update, the touchscreen will flip upside-down. If that’s a bother to you, you can flip it by adding lcd_rotate=2 to the last line in the config file in the boot folder, using the following command: sudo nano / | ||
| + | ==== Step #3: Install OpenHAB ==== | ||
| + | {{: | ||
| + | Now it’s time to install our home automation control software, OpenHAB, and the OpenHAB addons we’ll be using. | ||
| + | * Open a command line on the Pi, and enter the following commands: sudo mkdir / | ||
| + | Now we'll enter a few more commands to configure OpenHAB to run at startup: sudo wget http:// | ||
| + | We'll also need to install the OpenHAB MQTT addons, since that's the protocol we'll be using to communicate with our LED strip: sudo wget https:// | ||
