In this little project,  the RSSI value (detected by a small python script)  is used to control 3 LED’s on an Arduino. The LED’s are used to indicate the proximity (in terms of Far Away, Slightly Closer and Very Close) of a paired device relative to the PC running the script. The python script can also send a message to Twitter when the paired Bluetooth device is in close proximity to the PC.

The Arduino Sketch and companion Python script are both in the zip file rssitracker.zip which can be downloaded from the Software page.
