Summary

This circuit integrates a KY-023 Dual Axis Joystick Module, an Arduino Nano microcontroller, an NRF24L01 wireless transceiver module, and a power source consisting of two 18650 batteries. The joystick module provides analog input to the Arduino Nano, which can process the input and communicate wirelessly via the NRF24L01 module. The 18650 batteries supply power to the circuit, with voltage regulation provided by the Arduino Nano for the NRF24L01 module.
