Bluetooth Shield for Arduino

This Bluetooth Shield is a serial-port Bluetooth (Slave/Master) breakout board designed for easy integration with Arduino. It can be stacked directly onto an Arduino board and uses the UART interface for Bluetooth communication.

The shield is composed of two main parts: a Bluetooth Bee module and an XBee Shield. The Bluetooth Bee wireless module supports baud rate configuration, allowing it to work seamlessly with an XBee adapter. When used with an XBee Arduino controller base, the shield enables convenient and reliable Bluetooth wireless control for Arduino projects.
