Summary of the Circuit

This circuit integrates an Arduino Nano microcontroller with an NRF24L01 wireless transceiver module and an MPU6050 accelerometer/gyroscope module. The Arduino Nano serves as the central processing unit, interfacing with the NRF24L01 for wireless communication and the MPU6050 for motion sensing. The circuit is powered by two 18650 Li-ion batteries connected in series or parallel (not specified), providing power to the Arduino Nano and through it to the other modules. The Arduino Nano communicates with the NRF24L01 and MPU6050 using SPI and I2C protocols, respectively.
