Arduino-based "kitchen" timer

Arduino-based "kitchen" timer, originally uploaded by KayDub.

A demo of the packaged version of my Arduino-powered timer. A simple button/led system to create a virtually unlimited number of countdown alarms. My first use of an Arduino Pro, powered via a LiPoly rechargeable battery. Plays simple songs via a piezo, and blinks led’s to visually mirror the notes. Also monitors supplied battery voltage, and cycles the LEDs when battery will need recharging.
