My car does not have bluetooth and I was thinking of a project where I can play songs from my cell phone through a bluetooth device using car stereo.
So my cell phone would connect to the bluetooth device which in turn would be connected to car's stereo. I am also planning to put an lcd screen that would scroll the songs name.
can a bluetooth receiver connect to a microcontroller???
sparkfun.com sells bluetooth modules which connect directly to micro controllers. You MAY be able to find a commercial unit which does what you want, such a product I'm sure is already on the market.
