Fred 453 Posted June 6, 2013 Share Posted June 6, 2013 There's a few threads on MSP430 audio playback and they've prompted me to wonder what's the best way to actually play the audio (i.e. drive a speaker, piezo) for a simple battery-powered kid's toy? A lot of stuff I can find on audio generation stops at the output to an amplifier. I've seen a few examples of directly driving a speaker (via a low pass filter) from a microcontroller pin but that doesn't seem ideal. The background to this: My 1.5 year old son likes sitting on and starting my motorbike and I've just got him his first balance bike. I'm sure he'd love a starter button and some engine noises on his bike. I'm obviously not after great audio quality, just reasonable (ideally adjustable) volume and battery life for a toy.
