I love using things for their unintended purposes, and LEGO is no exception. I wanted to use the new LEGO Dots line and add some LEDS to give it some flare.
You have a few different options to connect the LED strip. I went with option 2 for this project.
The Pixelblazev2 and LED strip can be powered through the micro USB on the Pixelblazev2 controller. The USB power is connected internally to the 5v screw terminal, and the total current draw should be kept under 1.8A (it you aren't sure look at the power rating on the USB power supply you are planning on using).
Connect your power source to the Pixelblazev2 which will set the controller automatically to setup mode, the controller creates a new WiFi network that starts with "pixelblaze_" followed by a random hexadecimal number. Here you can configure the controller to run in either AP (Access Point) mode(which is what I did for this project).
Connect to your Pixelblazev2 network from a computer or mobile device, then a WiFi Manager screen should pop up on your computer or device. If the screen doesn't open automatically you can open a browser and go to http://192.168.4.1
Select the LED Type: APA102/SK9822/DotStar.
There are preset LED patterns, or if you want a challenge you can write your own patterns.
Advanced Mode: Writing your own patterns.
