Summary

The circuit in question is composed of an Arduino UNO, an Arduino Nano, two NRF24L01 wireless transceiver modules, a 5V relay, and an AITrip ADXL335 GY-61 accelerometer module. The Arduino UNO and Nano serve as the main microcontrollers for processing and controlling the various peripherals. The NRF24L01 modules enable wireless communication, while the 5V relay allows for controlling higher power loads. The ADXL335 module is used for sensing acceleration in three axes.
