This project aims to teach artists, and hobbyists in general, how to build their own MIDI controllers, with little or no prior knowledge in electronics and/or programming.
The "Nerd Musician Pro" is a project created by Gustavo Silveira. Visit the website for more nerd musical related tutorials!

Este projeto tem como objetivo permitir que artistas, e hobbystas em geral, possam aprender a construir os sues próprios controlaodres MIDI, com pouco, ou sem conhecimento prévio em eletrônica e/ou programação.
O "Fazendo Msica com Arduino" é um projeto idealizado por Gustavo Silveira. Acesse o site para mais tutoriais relacionados a mais nerdices musicais!

This sketch reads the Arduino's digital and analog ports and sends MIDI notes and MIDI control change. It was created by Gustavo Silveira in 2023. For more information and other projects, visit the following links:
If you are using this for anything other than personal use, don't forget to give credit.
Define your board by choosing one of the following options and uncomment the corresponding line:
#define ATMEGA328 1if using ATmega328 (e.g., Uno, Mega, Nano)#define ATMEGA32U4 1if using ATmega32U4 (e.g., Micro, Pro Micro, Leonardo)#define TEENSY 1if using a Teensy board#define DEBUG 1if you just want to debug the code in the serial monitor
If you are using buttons, ensure the following line is uncommented:
#define USING_BUTTONS 1If you are using potentiometers, ensure the following line is uncommented:
#define USING_POTENTIOMETERS 1Include the appropriate MIDI library based on your board selection.
Buttons:
const int N_BUTTONS = 3;
const int BUTTON_ARDUINO_PIN[N_BUTTONS] = { 2, 3, 4 };Potentiometers:
const int N_POTS = 2;
const int POT_ARDUINO_PIN[N_POTS] = { A0, A1 };For potentiometers, include the ResponsiveAnalogRead library:
#include <ResponsiveAnalogRead.h>In the setup() function, initialize the serial communication and configure the pins for buttons and potentiometers.
In the loop() function, call the buttons() and potentiometers() functions to handle the input and send the appropriate MIDI messages.
The buttons() function reads the state of each button, debounces the input, and sends MIDI note on/off messages.
The potentiometers() function reads the state of each potentiometer, smooths the input using ResponsiveAnalogRead, and sends MIDI control change messages.
The following functions handle MIDI messages for the ATmega32U4 board using the MIDIUSB library:
void noteOn(byte channel, byte pitch, byte velocity);
void noteOff(byte channel, byte pitch, byte velocity);
void controlChange(byte channel, byte control, byte value);- Ensure the correct board and USB port are selected in the Arduino IDE.
- Check for correct library installations.
- Use the serial monitor to debug and verify the outputs.
- Use a multimeter to check circuit continuity if hardware issues are suspected.
This sketch allows you to interface with buttons and potentiometers, sending MIDI messages for musical applications. Customize the code as needed for your specific project requirements.
