Arduino MPR121 Touch Piano

This project uses on off-the-shelf capacitive touch shield or module to provide touch-sensitive pads for a 12 (recommended for beginners) to 48 (advanced) note "piano". https://youtu.be/rq7UWVNde8M   These are the key Arduino tutorials for the main concepts used in this project: Adafruit MPR121 12-Key Capacitive Touch Sensor Breakout Tutorial Sparkfun MPR121 Hookup Guide Arduino Tone … Continue reading Arduino MPR121 Touch Piano

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
