This guide will not only show you how to make a DIY universal remote, we'll also show how to grab data using a logic analyzer, parse it with Jupyter notebooks, compress it to fit into our little CircuitPython boards, & take advantage of the Python eval function to dynamically load data into memory.
DIY Light-Up Kicks
The DIY Light-Up Kicks are high top sneakers embedded with a WS2812 Addressable LED Strip and a Qduino Mini Microcontroller. In this tutorial, we will go through the step-by-step process of building this project.
