Arduino Tone Polyphony – Part 4

In this final (for now) part of my Arduino Tone Polyphony project I'm returning to part 2 which was creating a stand-alone, full 12-note polyphonic tone keyboard with an Arduino Uno and committing it to an Arduino Shield using a proto-shield. Warning! I strongly recommend using old or second hand equipment for your experiments. I am … Continue reading Arduino Tone Polyphony – Part 4 →

Arduino Tone Polyphony – Part 2

There were two enhancements to my Arduino Tone Polyphony project I was keen to explore. One was to expand the MIDI range of notes and one was to "build in" a keyboard. I have managed to create an experimental version that can support four octaves over MIDI, but tuning needs some work, so I'm not ready … Continue reading Arduino Tone Polyphony – Part 2 →

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 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 →

Arduino Nano 12-Note Keyboard

This project builds on the Simple Arduino Music Keyboard but expands it to a full octave of chromatic notes. As there are more buttons this time, I've actually soldered this together onto a piece of stripboard and built in space to use an Arduino Nano as the controller. In Arduino Nano MIDI Keyboard I add MIDI out … Continue reading Arduino Nano 12-Note Keyboard →

Simple Arduino Music Keyboard

This project uses the Arduino tone() function to make a sound coupled with a set of eight buttons that act as a simple one octave music keyboard (with no accidentals). In Arduino Nano 12-Note Keyboard I extend this to 12 notes using an Arduino Nano and some stripboard. In Arduino Nano MIDI Keyboard I add MIDI out … Continue reading Simple Arduino Music Keyboard →
