Overview¶

This final project is based on a Musical Instrument Digital Interface (MIDI) controller. The base idea of this is a device that allows a wide variety of electronic musical instruments or sounds to be played at the press of some buttons. This project uses a mbed hooked up to a PC with the standard USB, and utilizes a C# application on Windows to receive serial port messages and plays sound files.

Components¶

• /users/4180_1/notebook/pushbuttons/
• /users/4180_1/notebook/rgb-leds/
• /users/4180_1/notebook/ulcd-144-g2-128-by-128-color-lcd/

Wiring¶

uLCD displays current Layer of sounds, and whether or not loops are on. Each layer allows for 8 different sound clips, with 3 layers total.

The two rows of four Push buttons trigger sound clips when pressed. The top two buttons activate loops, recording current sounds and then continuously plays them over and over. If pressed again, the loop stops.

LEDs are used to indicate if something is on or not, or show the layer.
