Arduino MIDI Master Volume Control

This project uses an Arduino Uno or Nano with a potentiometer to create a MIDI Master Volume Control. 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 the main concepts used in this project: … Continue reading Arduino MIDI Master Volume Control →

EuroRack 6HP MCU Experimenter Module

I've been following the work of HAGIWO for some time and always been really impressed with the breadth and range of modules they produce. I have noticed some patterns in their microcontroller based modules and so wondered if it was possible to build some kind of generic template PCB that would allow me to do … Continue reading EuroRack 6HP MCU Experimenter Module →

Nano MIDI Proto PCB Design

I wanted a simple way to prototype some circuits on an Arduino Nano - and thought I'd built up a prototyping board - but it turns out I haven't! I have an Arduino shield (more here) and a prototyping board for the XIAO (here) but so far not a Nano. This post fills that gap. … Continue reading Nano MIDI Proto PCB Design →

Proto Pedal PCB Design

One (other) thing I was toying with experimenting with is the whole world of DIY guitar pedals. I don't know much about them but wanted a platform I could use for experimentation. Part 1 - PCB Design and Introduction. Part 2 - PCB Build Guide. Part 3 - Proto Pedal Usage and Application Notes. I … Continue reading Proto Pedal PCB Design →

Arduino Direct Digital (Additive) Synthesis

This is actually a collection of previous projects with the code tidied up a little and combined to show a single sketch that can be configured for either PWM, an R2R ladder or the MCP4725 I2C DAC. There isn't really anything here that hasn't been talked about before somewhere, but hopefully this can act as … Continue reading Arduino Direct Digital (Additive) Synthesis →

Arduino Guess the Frequency Game

This is a bit of an odd one, but I was asked to put something musically related together as a game to get in the spirit of the season, so I thought something along the lines of an Arduino adjustable tone generator with the aim being the player has to tune it by ear to … Continue reading Arduino Guess the Frequency Game →
