this a simple sound generator based on 8-pin SD Audio Player. It is built with an Atmel ATtiny861 microcontroller and an SD memory card. The tiny861 has fast PWM outpus like tiny85 so that it can generate clear sound compared to any other AVR chips. On 20-pin device, many GPIO pins are available. It enables to control the sound generator by external signals. Because it can be controlled with ease, this project is usable as sound module for toys, tone ringers, amusement machines and gadgets.
