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 →

OLED MIDI Display

Following on from my experiments with colour TFT displays, this project takes a cheap monochrome OLED display and puts it to use with MIDI. In Part 2 I almost manage to get two displays working! https://youtu.be/Ayp-f-wmYkE Warning! I strongly recommend using an old or second hand keyboard for your MIDI experiments. I am not responsible for … Continue reading OLED MIDI Display →

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 →

Adafruit Feather MIDI, Music and LEDs

In my last post using the Adafruit Feather, I described how to get the MIDI and Music Maker FeatherWings working together. This time I'm adding in the CharlieWing LED module. https://youtu.be/Oi54vxumLFc 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! … Continue reading Adafruit Feather MIDI, Music and LEDs →

Adafruit Feather MIDI and Music

I've wanted an excuse to play with some of the Adafruit Feather lines of boards for a while, so I finally dipped in a bought a board and a couple of add-ons. You can get most of their range in the UK from Pimoroni, The Pi Hut, and others (I'm not affiliated with any of … Continue reading Adafruit Feather MIDI and Music →

Arduino MIDI VS1053 Synth – Part 2

I'm planning a use of the VS1053 shield but need to be able to pre-select which instruments to play and which channels to respond to. This revisits the Arduino MIDI VS1053 Synth and adds that functionality. Warning! I strongly recommend using an old or second hand keyboard for your MIDI experiments. I am not responsible for any … Continue reading Arduino MIDI VS1053 Synth – Part 2 →

Arduino MIDI Filter

I am working on something that might allow several of my projects to come together, but one issue I'm having is the overheads of processing unnecessary MIDI traffic are causing delays in playing for some of the modules. So I thought I'd create a MIDI filter that can be used to see all the traffic … Continue reading Arduino MIDI Filter →

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 →
