Circuit Documentation

Summary

This document provides a detailed overview of a circuit that includes an Arduino Nano as the central microcontroller, interfaced with various components such as an LED, a resistor, a rocker switch, an NRF24L01 wireless communication module, an MPU6050 accelerometer and gyroscope module, and a power source (18650 battery in a holder). The circuit is designed to control an LED, read sensor data from the MPU6050, and communicate wirelessly using the NRF24L01 module. The Arduino Nano is powered by the 18650 battery, and it also provides power to the NRF24L01 and MPU6050 modules.

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 code is a template for the Arduino Nano and does not contain any functional code. It provides the basic structure for an Arduino sketch with setup() and loop() functions, where initialization code is placed in setup() and the main code that runs repeatedly is placed in loop(). Additional code should be added to control the LED, read data from the MPU6050, and handle wireless communication with the NRF24L01 module.
