Circuit Documentation

Summary

This circuit integrates an Arduino Nano microcontroller with various sensors and displays, including a GPS module, a barometric pressure sensor, a seven-segment display, a bar graph, and a toggle switch. The circuit is powered by a 5V battery through an Adafruit Mini Lipo charger. The Arduino Nano is programmed to interface with these components, providing a comprehensive embedded system for data acquisition and display.

Code Documentation

Arduino Nano Code

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

}

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

}

This code is a basic template for the Arduino Nano. The setup() function is where you initialize your components and settings, and the loop() function is where the main logic of your program runs repeatedly. You can add your specific logic to interface with the connected components in these functions.
