LEDs, Microcontrollers, and Microphones - The World’s Most Complicated Backsplash?

Join me as I discuss my latest project - building a glass tile backsplash with individual LEDs on each tile. I'll also be adding touch sensors to each tile to implement touch feedback, using a distributed processing technique, and leveraging the existing LED communication protocol. We'll cover electronics design, LED protocols, PCB fabrication, soldering, and... home improvement? To do this, I'll be using a distributed network of microcontrollers, around 160 microcontrollers. Each microcontroller will read the values from two microphones (320 total!), perform computations, and send the data to the main controller so that the LEDs can be controlled in unique ways based on touch feedback. Since this is a DIY project with limited funding, it was necessary to use one of the cheapest microcontrollers available, the Puya PY32. I'll discuss some of the benefits and challenges of these devices. I'll also cover design and construction of the prototype board, including the electronic CAD schematic, circuit board layout, surface mount (SMD) soldering, and more. This is part of a larger series covering the build, so be sure to like and subscribe to get all the updates! 00:00 Introduction 00:34 The Concept 02:00 Overall Implementation 04:09 Drawing out the Implementation 05:03 How the Neopixels Work 08:35 How to Listen to 320+ Microphones 10:29 Microcontroller Selection 12:02 Hardware Selection 13:47 PCB Selection 15:19 Other Technical Detail 16:30 KiCAD Schematic and Layout 19:28 A Brief Discussion of Software and the Puya PY32 24:02 Making a Solder Paste Stencil 25:08 Assembling the Prototype 26:42 Conclusion
