Circuit Documentation

Summary

This circuit is designed around an Arduino Nano microcontroller and includes a variety of components that interact with the microcontroller. The circuit is powered by a 7.5V battery pack consisting of five AA batteries. A rocker switch (SPST) is used to control the power flow to the circuit. The Arduino Nano interfaces with an nRF24L01 wireless communication module and two analog joysticks (Wokwi compatible). The nRF24L01 module allows the Arduino Nano to communicate wirelessly, while the analog joysticks provide user input through two axes and a selection button.

Component List

Arduino Nano
