but a whole bunch of Atmel microcontrollers have a very cool feature hidden away in their datasheets. Most of them – everything from the ATMega 168, 328, 32u4, to the ATtiny85 and 84 have a ...

While the ATMega328 is “mega” for a microcontroller ... which really puts the Atmel chip through its paces. The audio is played through a 512-byte buffer and an interrupt triggers the ...
