Summary of the Circuit

This circuit integrates an Arduino Nano microcontroller with several peripherals: an HC-05 Bluetooth module for wireless communication, an MPU-6050 accelerometer and gyroscope for motion sensing, a KY-023 Dual Axis Joystick Module for manual input, and a 9V battery with a rocker switch for power supply. The Arduino Nano serves as the central processing unit, interfacing with the sensors and the Bluetooth module to possibly collect data and control or communicate with other devices.

Documented Code

Arduino Nano Code (sketch.ino)

void setup() {
  // put your setup code here, to run once:

}

void loop() {
  // put your main code here, to run repeatedly:

}

This is the basic structure of an Arduino sketch, with two primary functions: setup() and loop(). The setup() function is called once when the sketch starts and is used for initializing settings, pin modes, starting libraries, etc. The loop() function is called repeatedly and contains the main logic of the sketch. The provided code is a template and does not contain any specific functionality. Additional code would be required to initialize and use the connected modules and sensors.
