Circuit Documentation
Summary
This circuit integrates an NRF24L01 wireless transceiver module with an Arduino UNO microcontroller board, a joystick module, and a battery pack to provide power. The NRF24L01 module enables wireless communication, while the joystick module allows for user input. The Arduino UNO serves as the central processing unit, interfacing with both the NRF24L01 and joystick module. The battery pack supplies the necessary power to the Arduino, which in turn powers the other components.

Additional Notes
- The provided code is a template and does not include specific functionality. It needs to be populated with the logic for initializing the NRF24L01 module, reading the joystick inputs, and implementing the desired behavior.
- The IRQ pin of the NRF24L01 is not used in this circuit.
- The joystick's SW pin is used for the pushbutton feature, which can be programmed to trigger events when pressed.
- The battery pack should provide a suitable voltage for the Arduino UNO's Vin pin, typically between 7V to 12V.
