Anyone who is a bit interested in electronics and hobby circuit assembling would have came across the readily available Bluetooth miniature modules which could be interfaced to a PIC microcontroller circuit and create devices that could communicate with any other Bluetooth enabled devices. This could be interfaced to our Mobile Phone applications in any platform that supports Bluetooth interfacing and create a wide variety of applications like Bluetooth controlled toy car (this project details are already available freely). You can find a lot more of applications for this mobile – circuit combination, both useful and amazing.

I have found the Car Remote Project source code on net. It was helpful for me. Now I think I can develop my own device that can control a light or fan speed from my mobile. Thanks!
