Inspired by sitcoms and cartoons. I thought it would be fun to be able to add sound effects to my own life. So I made a sound effects suit jacket. The sound samples are triggered by a control panel with 4 buttons (3 for samples, 1 for changing sound banks). And then being played from an Arduino + Wave Shield through a portable speaker. All the hardware is kept within the inner jacket pockets while in use.
Uses an Adafruit Wave Shield! Adding quality audio to an electronic project is surprisingly difficult. Here is a shield for Arduinos that solves this problem. It can play up to 22KHz, 12bit uncompressed audio files of any length. It’s low cost, available as an easy-to-make kit. It has an onboard DAC, filter and op-amp for high quality output. Audio files are read off of an SD/MMC card, which are available at nearly any store. Volume can be controlled with the onboard thumbwheel potentiometer.
