But what if you want to play real songs or sounds?
The most obvious answer is to record your sound as an MP3 file and play it from
the PICAXE chip.
Unfortunately, though, MP3 files are very large and no
microcontroller, PICAXE included, has sufficient memory to store many files.
Fortunately a company called FDTI (www.ftdichip.com), based in Glasgow, Scotland has produced a very
neat ‘VMUSIC2’ module ideal for this type of application.
The VMUSIC2 module
The FTDI VMUSIC2 module is shown below. It is supplied in a
neat plastic enclosure but this is very easy to pop open if you want to look
inside! The enclosure has a bi-colour LED, a headphone socket and USB thumb
drive socket on the front, while on the rear there’s an 8 wire connector to
connect power and control signals.
Here's the VMUSIC2 module, shown at left with the earphone and USB sockets and below opened out to show the workings. Don't worry about the unused pins.
Between the two pics are the connections to the VMUSIC2.
