Circuit Documentation

Summary

This document provides a detailed overview of a circuit that integrates an Arduino UNO microcontroller, an RFM95 LoRa module, and an inductor. The Arduino UNO serves as the main controller, interfacing with the RFM95 module for wireless communication. The inductor is connected to the antenna pin of the RFM95 module.

Code Documentation

Arduino UNO 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 UNO. The setup() function is where you initialize your components and configurations, and the loop() function is where the main logic of your program runs repeatedly.
