AD9833 Signal Generator – Part 2

This is the next stage of experimenting with the AD9833. This time adding some control to the device. https://youtu.be/yoGaWoMqsuA 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 main concepts used in … Continue reading AD9833 Signal Generator – Part 2 →

AD9833 Signal Generator

I've picked up some cheap AD9833 based signal generator boards which look particularly interesting as they are programmable frequency generators capable of generating a sine, square or triangle wave at frequencies up to 12.5MHz and are controlled using the SPI bus from the Arduino. In part 2, I add some simple controls. In this part, … Continue reading AD9833 Signal Generator →

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 →

PC USB to DIN MIDI IN

My PC USB MIDI interface is wired into my LoFi Orchestra at present and I don't have another one, but having already done the hard part of getting the software USB MIDI stack up and running I thought it would be fairly easy to add an actual MIDI DIN plug to create a (one-way - … Continue reading PC USB to DIN MIDI IN →

MCP4725 MIDI Sample Player

This is an update to my MCP4725 Sample Player to have it "playable" over MIDI rather than be triggered via a button. 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 main … Continue reading MCP4725 MIDI Sample Player →

MCP4725 Sample Player

This is another chance to get out the MCP4725 digital to analogue converter module. This time I want it to play a sampled sound as a type of "effect" based on a trigger. In the next part, I add MIDI support. https://youtu.be/LtqQGB5PInM These are the key Arduino tutorials for the main concepts used in this … Continue reading MCP4725 Sample Player →

PC USB to Arduino Serial MIDI – Part 2

Having built a stand-alone PC USB to Arduino Serial MIDI link, I thought it might also be useful to have a shield that allows a direct PC USB link to the Arduino too. Warning! I strongly recommend using an old or second hand keyboard for your MIDI experiments. I am not responsible for any damage to … Continue reading PC USB to Arduino Serial MIDI – Part 2 →

PC USB to Arduino Serial MIDI

Whenever I've needed to get a computer to drive my MIDI setup I've wheeled out my Roland UM-ONE PC USB MIDI interface which gives my laptop a MIDI IN and OUT DIN plug. But if I want to get my PC to drive the Arduinos I need to then plug the UM-ONE into one of … Continue reading PC USB to Arduino Serial MIDI →

TFT MIDI Display – Part 3

This display is inspired by the sound and light show at the end of Close Encounters of the Third Kind. It uses the TFT MIDI Display once again. https://youtu.be/hEpZ7Zy03Vo 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 … Continue reading TFT MIDI Display – Part 3 →
