microcontrollers

[spacebug]

There's a little interactive art project I want to make- I want to take an existing phone, and have each of the number keys trigger a sample (or mp3, or whatever, quality isn't super important) through the receiver's speaker. If possible, I think it'd also be fun to put a proximity sensor on the ringer so that it rings when someone approaches it. I know this should be do-able with a microcontroller, but I have no experience with them and very little programming experience (though I'm working my way through MAX/MSP, which, while not a true programming language, can communicate with ardunios.)

Any advice or online resources from you Makers?

Old phone ringers take fairly high current- 70-120VDC, total around 300mah.

I found some circuit diagrams for building your own ring generator, but I'd try and buy one.
