Using Bluetooth and an Android phone for debugging Arduino sketches
I bought a Bluetooth module a few months ago and never really tried to use it because in my mind it would be another module that would require hours digging the internet to find libraries, and some code sample to get me started.
Only after reading Stan’s post about Bluetooth modules I realized how easy is to get them working and how useful they can be to troubleshoot projects that require movement (like robots).
Bluetooth basically makes your serial port wireless and open a whole new set of possibilities with two way communication between your Arduino and a Bluetooth enabled device.
