Toy Keyboard Matrix Decode with the Pi Pico

I'm always on the look out for discarded music keyboards that I might be able to do something with, so when I came across this thrown out in the street I claimed it to take a look. This shows how I used a Raspberry Pi Pico to decode the keyboard part and turn it into … Continue reading Toy Keyboard Matrix Decode with the Pi Pico

Arduino Tone Polyphony – Part 5

Ok, I thought I’d done with Arduino Polyphony for the time being, but something else came up today that I wanted to try. My post got a mention on the Hackaday blog and one of the comments has led me to a tweak that helps the tuning a little. https://youtu.be/lEaZhnjikfs Warning! I strongly recommend using old or … Continue reading Arduino Tone Polyphony – Part 5

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 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
