Simple MIDI Touch Button Keyboard

I've grabbed some very cheap TTP223-based touch pad PCBs so this is showing how they can be used as a replacement button in a simple Arduino MIDI controller. Warning! I strongly recommend using old or second hand equipment for your experiments. I am not responsible for any damage to expensive instruments! These are the key … Continue reading Simple MIDI Touch Button Keyboard →

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 →

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 Touchscreen X-Y MIDI Controller – Part 2

Whilst being able to use a cheap touchscreen with a DIY shield gets me so far, there are a number of cheap touchscreen shields around and I've had one for a while, but not managed to really get it going. I thought it was perhaps about time to see what I could do, so I … Continue reading Arduino Touchscreen X-Y MIDI Controller – Part 2 →

Arduino Touchscreen X-Y MIDI Controller

I have a list of other projects I'd like to use my cheap touchscreen MIDI controller for. For details see the original discussion here: Arduino Touchscreen MIDI Controller. In this project I turn it into an "X-Y" controller - essentially a two-dimensional potentiometer. Moving in the Y direction changes one value and moving in the X … Continue reading Arduino Touchscreen X-Y MIDI Controller →

Arduino Touchscreen MIDI Controller – Part 2

Here is another format for my newly found cheap touchscreen MIDI controller. This time, presenting twelve virtual "slider pots" for use as MIDI controllers. https://youtu.be/FHu0BoCBEAw Warning! I strongly recommend using old or second hand equipment for your experiments. I am not responsible for any damage to expensive instruments! These are the key Arduino tutorials for … Continue reading Arduino Touchscreen MIDI Controller – Part 2 →

Arduino Touchscreen MIDI Controller

I picked up a cheap touchscreen display online, but it wasn't easy to work out how to get it all working. Full details can be found here, so having got to this point I thought I'd start to explore its use as a MIDI controller. Here are some follow-up projects based on this touchscreen: Arduino … Continue reading Arduino Touchscreen MIDI Controller →
