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 →

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 →

Arduino Nano MIDI Keyboard

This project takes the Arduino Nano 12-Note Keyboard and updates it with MIDI capability! https://youtu.be/91Q-Ml86JKA 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! Parts list An existing Arduino Nano 12-Note Keyboard 2x 220 resistor male header pins 5 pin … Continue reading Arduino Nano MIDI Keyboard →
