Arduino R2R Digital Audio – Part 3

So this is where we start to get closer to some proper direct digital synthesis using the hardware developed in part 1 and moving on from the timer-driven code developed in part 2. In Arduino MIDI R2R Digital Audio I add MIDI. https://youtu.be/1MPNHMQ-2vs The essence of this project is to update the code so that rather … Continue reading Arduino R2R Digital Audio – Part 3

Arduino R2R Digital Audio – Part 2

Building on the Arduino R2R Digital Audio project, this uses the Arduino Timer functions to run our code in a more accurate and useful way.  I've now also added some potentiometers to my shield and a jack output socket. In Arduino R2R Digital Audio - Part 3 the code is developed further to support wavetable synthesis. These … Continue reading Arduino R2R Digital Audio – Part 2

Arduino MIDI Relay Drumkit

This projects links up the ideas from the Arduino Relay Bolero and Arduino MIDI Tone Module projects to create a MIDI drumkit out of relays.  This builds on concepts we've already met in the above projects. In Arduino MIDI Relay Servo Drumkit the kit expands to include "servo cymbals". https://youtu.be/3m7usT0Gd5Q Warning! I strongly recommend using an old or … Continue reading Arduino MIDI Relay Drumkit

Arduino MIDI Note Monitor

This project shows you which note is being playing, within a single octave (white notes only!), by lighting up a different LED for each note. I develop more sophisticated LED visualisations in Wemos MIDI LED Matrix. The Arduino MIDI Channel Monitor shows you which channels are being used. https://youtu.be/0oSYtyVBxfE Warning! I strongly recommend using an old … Continue reading Arduino MIDI Note Monitor

Simple MIDI Monitor – part 2

This is a repeat of the Simple MIDI Monitor but using a home made MIDI receive circuit on breadboard and then stripboard. https://youtu.be/ZmuelybXtzY 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! These are the key Arduino tutorials for the … Continue reading Simple MIDI Monitor – part 2
