Wemos MIDI LED Matrix

Building on the ideas from the Arduino MIDI Note Monitor this project uses an LED matrix, which is an 8x8 grid of LEDs. You can get these as shields for the Arduino, as individual units, as "backpacks" (i.e. modules to plug-in and use) and a whole variety of forms. Each will have a corresponding library to … Continue reading Wemos MIDI LED Matrix →

MIDI Patch Button

This project uses the Arduino MIDI Library again, as described in my previous project Arduino Simple MIDI Controller, alongside a button as input to provide a "hotkey" patch change message to your keyboard or synth. These are the key Arduino tutorials for the main concepts used in this project: Arduino Button The Arduino MIDI Library … Continue reading MIDI Patch Button →

Arduino Relay Bolero

There are a number of add-ons you can get for Arduino projects that make a rather satisfying sound when activated. This project uses a relay board, which is mean to allow an Arduino to switch a higher power load (such as turning on a light bulb or similar), but I'm just using the click as … Continue reading Arduino Relay Bolero →
