Summary of the Circuit

This circuit integrates an Arduino Nano microcontroller with a BNO055 absolute orientation sensor and an HC-05 Bluetooth module. The Arduino Nano serves as the central processing unit, interfacing with the BNO055 sensor to obtain orientation data and communicating wirelessly via the HC-05 Bluetooth module. The circuit is designed to capture orientation data and transmit it over Bluetooth to a remote receiver.
