Summary

This circuit involves an Arduino UNO microcontroller interfacing with an MPU6050 accelerometer and gyroscope sensor, an HC-05 Bluetooth module, several flex resistors, and standard resistors. The circuit is powered by a 9V battery. The Arduino UNO reads data from the MPU6050 and flex resistors, and communicates with the HC-05 Bluetooth module to transmit data wirelessly.
