# Drumpad

Drumpad is an Ardunio-based music generator built for my Programming and Physical Computing project, Module 2 (Smart Environments) of Creative Technology BSc at the University of Twente.

## Toolkit

### Materials

- Arduino Uno

- 4 × 1MΩ resistors for capacitive sensors

- 4 × 330Ω resistors for LEDs

- 4 × conductive input surfaces

- 4 × LEDs for output

- 2 × potentiometers

### Sounds

## How it works

### Fritzing structure

### Directory Structure

```

.

├── arduino

│   ├── CapacitiveSensor.h

│   └── drumpad.ino

└── processing

    ├── drumpad.pde

    ├── data

    ├── exports

    └── samples

	    └── instrument_name

		    └── 0.wav … n.wav

```

### Instruments

Drumpad automatially fetches instruments from the `processing/drumpad/samples` folder. Each instrument should have a corresponsing folder with WAV files from 0 to n, based on the number of input capacitive sensors. This means that it's completely agnostic to the instruments, users have the ability to add or remove instruments from their collection.

### Recording

Users can press the "Record" button to start recording their music. On completion, a data file with the extension `.drumpad` is created in the `processing/drumpad/exports` folder. When a user goes to the "Import" screen, they see a lit of their recordings, which then can be played.
