First I just have to say that this site deserves a lot of credit for getting me into robotics. I only had an inkling of an interest in robotics until I built the "My First Robot" so props on that.
To my question though, I found this cheap santa toy for a dollar with motors and a speaker for saying some santa related phrase and I want to try to make the speaker play either from an ipod or some sort of microcontroller sound module or something. How could I do this?
Also on the speaker it says GW 8 ohms 0.5 watts.
If you did the start here
If you did the start here robot project, then you should be familiar with the PICAXE. Take a read through PICAXE Manual 3, which explains how to interface the PICAXE (or most microcontrollers) to a variety of devices, including a speaker.
You can use the PICAXE sound and tune commands (check PICAXE Manual 2) to produce some simple sounds.
If you want to connect a speaker to an iPod or anything else with an audio jack out, you could try just connecting the leads of the speaker to an audio jack. It may not be very loud, and I’m not sure how much power the iPod puts out. Hopefully half a Watt would not be a problem, but try at your own risk. You could use an audio amplifier in between your iPod or other source and the speaker.
If you are asking how to interface your iPod with a microcontroller so you can play sound clips on command, that is a much more complicated topic.
Take a look…
Also take a look at this page. It compares a couple of options regarding sound playback with microcontrollers. Personally I’ve sucessfully manage to use the WTV020-SD-16P sound module that is pretty inexpensive, but beware DO NOT buy this module in the WRONG mode. For you to be able to control it with a microcontroller you’d get the serial version.
Thanks
Thanks a ton I’ll have to check it out.
Well, I learn how to use
Well, I learn how to use speakers with arduino with this “article”.

It’s a Brazilian website, so it’s written in portuguese, but the code is easy to understand, and the code comments are in english :D.
