Summary of the Circuit

This circuit is designed to interface an Arduino Nano with an NRF24L01 wireless transceiver module and a KY-023 Dual Axis Joystick Module. The Arduino Nano serves as the central processing unit, controlling the NRF24L01 for wireless communication and reading inputs from the joystick. A 12V battery provides power to the system, with a rocker switch included to control power delivery to the Arduino Nano. The NRF24L01 is powered by the 3.3V output from the Arduino Nano to match its operating voltage.
