Inexpensive tune playback with an ATtiny85
Date Posted:24 July 2012
With only an Atmel ATtiny85 microcontroller, some flat piezo elements and a coin cell battery you have enough electronics to create sounds and play a tune similar to those in a musical greeting card. The tune to play originates from a midi file, and is modified with a python script which results in code that can be added to the software which is uploaded to the MCU. And the results are pretty good:
This type of project could also be used to add sounds to stuffed animals, LEGO creations and anything else you can come up with. So to get started visit John's instructions here. And for more news, updates and items of interest, please follow us on twitter, Facebook and Google+.
