## Description

Want to communicate with your Arduino wirelessly? Don't want the complication of WiFi? Our Bluetooth Shield plugs right in and lets you send and receive data and commands from your sketches. You don't even need to do anything fancy in your sketches, because the Bluetooth link acts as a serial port: you just pair it with your computer, then you can simply use "Serial.read()" and "Serial.write()" as normal!

Please note that this shield is not compatible with iOS devices as they don't support the SPP (Serial protocol over Bluetooth).
