Hardware

Overview

This software requires two boards, an Arduino single-board computer and a second board with MIDI connectors and circuitry, buttons and knobs.

Arduino

This software has been tested extensively with the Arduino Uno Rev 3, but I expect it will work fine with many other Arduinos. The MIDI Shield board is laid out to mount to the standard Arduino layout, so it will not work with Arduinos laid out differently, such as the Arduino Mega and Arduino Mini. Below is a list of some boards I expect will work well for the sequencer.

• Arduino Uno
• Arduino Duemilanove
• Arduino Diecimila

You can find more information at the Arduino Board Page.

MIDI Shield

The SparkFun MIDI Shield adds the following to the Arduino:

• MIDI In connector and circuitry
• MIDI Out connector and circuitry
• 3 momentary pushbuttons
• 2 potentiometers (knobs)

Suppliers

• AdaFruit is a pretty good source for Arduino boards
• Radio Shack also stocks the Arduino Uno in many of their stores, but it is more expensive
• SparkFun is a good place to get the MIDI Shield
• Karlsson also carries it
