Arduino MIDI 7 Segment Controller – Part 2

As mentioned in my previous post,  the Arduino MIDI 7 Segment Controller is ripe for turning into a self-contained module.  To keep it all relatively small, I opted to build an add-on board for an Arduino Nano. Warning! I strongly recommend using old or second hand equipment for your experiments.  I am not responsible for any … Continue reading Arduino MIDI 7 Segment Controller – Part 2 →

Arduino Light Mozzi Generator – Part 2

I've spent a fair bit of time playing with the Control_Echo_Theremin example and finally committed it to stripboard. I was originally aiming for a fully self-contained module, speaker and all, but after a day or so trying to find a simple amplifier that works well with a PWM output, I've put that on hold for … Continue reading Arduino Light Mozzi Generator – Part 2 →

LOLShield MIDI Lighting Effects

This project goes back to the LOLShield and uses it to trigger some LED animations in response to MIDI events. https://www.youtube.com/watch?v=Hu4hc7NGaGI&feature=youtu.be 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 … Continue reading LOLShield MIDI Lighting Effects →

JQ6500 MIDI MP3 Player Module – Part 2

Having played with my JQ6500 a little now, I just wanted to finish the project by building a shield to support the module's use with an Arduino Uno. 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 JQ6500 MIDI MP3 Player Module – Part 2 →

OLED MIDI Display – Part 2

As I mentioned in my previous post, it should be possible to connect multiple displays to the same microcontroller. This projects looks into that in a bit more detail. Spoiler - it almost works, but has software limitations!  Read on for details. Warning! I strongly recommend using an old or second hand keyboard for your MIDI … Continue reading OLED MIDI Display – Part 2 →

MCP4725 Digital to Analog Converter – Part 3

My plan was always to try to use my MCP4725 board with Mozzi eventually, but there is one thing I came to realize that has stopped that ambition.  You can't talk I2C from an interrupt routine using the standard Arduino Wire libraries.  Mozzi uses an interrupt routine to output the audio samples at the required … Continue reading MCP4725 Digital to Analog Converter – Part 3 →

Keyboard MIDI Matrix Decode

Following on from my Keyboard Matrix Decode I've now added MIDI out!  So I have a full sized MIDI controller keyboard for the cost of a cheap Arduino Nano clone and a couple of passive components! https://youtu.be/kqcfxiKIzi4 Warning! I strongly recommend using an old or second hand keyboard for your MIDI experiments.  I am not responsible for … Continue reading Keyboard MIDI Matrix Decode →
