Arduino MIDI Relay Drumkit

This projects links up the ideas from the Arduino Relay Bolero and Arduino MIDI Tone Module projects to create a MIDI drumkit out of relays. This builds on concepts we've already met in the above projects. In Arduino MIDI Relay Servo Drumkit the kit expands to include "servo cymbals". https://youtu.be/3m7usT0Gd5Q Warning! I strongly recommend using an old or … Continue reading Arduino MIDI Relay Drumkit →

Arduino MIDI Note Monitor

This project shows you which note is being playing, within a single octave (white notes only!), by lighting up a different LED for each note. I develop more sophisticated LED visualisations in Wemos MIDI LED Matrix. The Arduino MIDI Channel Monitor shows you which channels are being used. https://youtu.be/0oSYtyVBxfE Warning! I strongly recommend using an old … Continue reading Arduino MIDI Note Monitor →

Arduino MIDI Tone Module

Now we are starting to do something useful with the MIDI receiving code from our Simple MIDI Monitor - this project gets it to play a note. It combines the MIDI monitor with the Simple Arduino Music Keyboard but instead of having keys to trigger notes, we are listening for MIDI messages. In Arduino Multi MIDI Tone Module … Continue reading Arduino MIDI Tone Module →

Simple MIDI Monitor – part 2

This is a repeat of the Simple MIDI Monitor but using a home made MIDI receive circuit on breadboard and then stripboard. https://youtu.be/ZmuelybXtzY Warning! I strongly recommend using an old or second hand keyboard for your MIDI experiments. I am not responsible for any damage to expensive instruments! These are the key Arduino tutorials for the … Continue reading Simple MIDI Monitor – part 2 →

Simple MIDI Monitor

This project is an example of receiving MIDI data. The simplest version of this project uses a MIDI shield that you can buy quite cheaply online. In Simple MIDI Monitor - part 2 I build a relatively simple MIDI in interface on breadboard or stripboard, but it is more involved than the few resistors and … Continue reading Simple MIDI Monitor →

Arduino MIDI Touch Piano

Just to complete the set, this is the Arduino Touch Piano – Part 2 stripboard version generating MIDI rather than tones. https://youtu.be/lJJe-0p2Y7k Warning! I strongly recommend using an old or second hand keyboard for your MIDI experiments. I am not responsible for any damage to expensive instruments! This builds on all the knowledge gained so far … Continue reading Arduino MIDI Touch Piano →

Arduino Touch Piano – Part 2

This is a minor update to the Arduino Touch Piano. I have some conductive copper tape so wanted to make an actual keyboard shape for the touch piano. But adding copper has made the sensing a lot more unreliable, so one trick the Capacitive Sensor library suggests improves reliability is to add a small capacitor between … Continue reading Arduino Touch Piano – Part 2 →

Arduino Touch Piano

This is another variant of the Simple Arduino Music Keyboard but this time using touch capacitive sensors. Basically a keyboard with touch sensitive keys. This generates a tone internally, but it would relatively easy to change it out output MIDI commands. In Arduino Touch Piano - Part 2 I update the circuit for better performance and build … Continue reading Arduino Touch Piano →

Arduino LDR Pianola

This project uses light-dependent resistors to build a pianola roll by detecting light and dark on a piece of paper to play a MIDI note. This one is a bit fiddly, but in terms of building the circuit and understanding the code, I've kept it in the "beginner" category. The issue is that it is … Continue reading Arduino LDR Pianola →

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 →
