Raspberry Pi Pico Capacitive Touch

I've now done a number of projects using capacitive touch, using a range of methods from native IO handling to the use of the MPR121 and off-the-shelf boards. Typically native IO methods require testing a response between a signal on one IO pin being received on another, with the timing of that response affected by … Continue reading Raspberry Pi Pico Capacitive Touch →

Arduino Touch Music – Revisited

This is a short demonstration of different ways to use my Touch Keyboard PCB, revisiting the following previous projects: Arduino MIDI Touch Piano Simple Arduino Music Keyboard Arduino MPR121 Touch Piano https://youtu.be/dc5dEkdLkxY Warning! I strongly recommend using old or second hand equipment for your experiments. I am not responsible for any damage to expensive instruments! This … Continue reading Arduino Touch Music – Revisited →

Touch Keyboard PCB – Part 2

This is the build guide for my Touch Keyboard PCB. Warning! I strongly recommend using old or second hand equipment for your experiments. I am not responsible for any damage to expensive instruments! If you are new to microcontrollers, see the Getting Started pages. Bill of Materials Touch Keyboard PCB (GitHub link below) Pin headers Build … Continue reading Touch Keyboard PCB – Part 2 →

Touch Keyboard PCB

Ever since experimenting with copper tape as a "touch keyboard" I wanted something a little more useful on a pcb. I always quite liked the design of the stylus keyboard for a Stylophone, so that was my starting point. I've not found anything "off the shelf" that wasn't part of another build, so I thought … Continue reading Touch Keyboard PCB →

Arduino MPR121 MIDI Touch Piano

A comment on the Arduino MPR121 Touch Piano pointed out that I never went as far as building a 48-note MIDI touch piano. In principle all the bits are there between that post and the Arduino MIDI Touch Piano so this post brings the two together to do just that. https://youtu.be/fdxiHUlXFbY These are the key Arduino … Continue reading Arduino MPR121 MIDI Touch Piano →

WS003 – Drums and Touch

This is the next of my worksheets collecting together a number of related projects with a single list of parts and a suggested "building order". This time all relating to touch interfaces or percussive projects. This worksheet links together the following projects: Arduino Relay Bolero Arduino MIDI Relay Drumkit Arduino MIDI Relay Servo Drumkit Instant … Continue reading WS003 – Drums and Touch →

Micro:bit Touch Piano

I've had a Micro:bit for a while now and recently found a "piano shield" from Keyestudio so thought I'd give it a go. These are the key tutorials for the main concepts used in this project: Micro:bit MakeCode Editor Keyestudio KS0440 Piano Module If you are new to the Micro:bit try the Micro:bit Getting Started … Continue reading Micro:bit Touch Piano →

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 →

Instant Touch Music

In this project, I'm looking at two "ready to go" boards that provide touch sensitive inputs that can be used to play music. First is the Adafruit Circuit Playground Express and then on to the Bare Conductive Touch Board. For a more "DIY" approach, see Arduino MPR121 Touch Piano. https://youtu.be/VCVvB2rTL4c These are the links to tutorials … Continue reading Instant Touch Music →

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 →
