WLED: How to setup and configure WLED

WLED Setup and Configuration

WLED is an awesome open source application created to control addressable LEDs (WS2811, WS2812b, WS2813, etc) from your iOS or Android smartphone, or literally any device which can send a command via http/https over a network! It runs on the ESP32 platform of microcontrollers, which although similar to the Arduino is different but mostly compatible […]

Building a Breadboard Synthesizer With a Raspberry Pi and an Arduino Uno

Build a Breadboard Synthesizer (Raspberry Pi Synthesizer) Hero

There’s a lazy stereotype about middle-aged men that says that all we want to do is tinker with our gadgets. I’m doing very little to challenge it, which I guess is how I came to weather the pandemic by trying to build my own Raspberry Pi synthesizer.  Building a breadboard synthesizer is a fun project […]

How Rotary Encoders Work – Electronics Basics

how rotary encoders work

In this tutorial, we’re going to learn how rotary encoders work! Rotary encoders (also shaft encoders) are a fantastic way to dial in a position, or determine the position of a shaft. This could be the position of a knob you are turning, or it could be an encoder connected to a stepper motor to […]
