Circuit Documentation

Summary

This circuit integrates an Arduino UNO microcontroller with an InvenSense MPU6050 accelerometer/gyroscope and an NRF24L01 wireless transceiver module. The Arduino UNO is powered by a 9V battery and provides regulated voltage to the other components. The MPU6050 communicates with the Arduino over the I2C protocol, while the NRF24L01 uses SPI for communication. This setup could be used for a wireless sensor application where the MPU6050 provides motion data that the Arduino processes and sends via the NRF24L01.
