Arduino Bluetooth Shield V2
Arduino Bluetooth Shield V2 , converting the standard bluetooth module it contains into a Shield form provides ease of use with Arduino. The Shield communicates using 2.4gHz radio frequencies and operates at 3.3V voltage. It has a communication range of over 10m in open areas. Communication can be established using TTL level serial communication pins. These pins can be selected by the user, and if software serial communication is desired, pins D0 to D7 are used, while for hardware serial communication, pins D0 and D1 are used.
