## Overview

This repository contains several small Arduino/IoT projects rather than one integrated application. The only inspected runtime shows an Odroid reading PM2.5 values over serial, then posting them to ThingSpeak and LINE Notify. The other projects are represented by their filenames only; with no README or source excerpts for them, their behavior and connections are left unspecified.

Main entry points: [`ProjectsArduino/Odroid_Project/odroidToThingSpeakAndLine.py`](https://github.com/meltzzuko/arduinoprojects/blob/main/ProjectsArduino/Odroid_Project/odroidToThingSpeakAndLine.py) (Serial polling loop)

### Other components

- **Serial input**
- **ThingSpeak**
- **LINE Notify**

## Connections

- Serial input → Serial polling loop: provides serial data (evidence: `ProjectsArduino/Odroid_Project/odroidToThingSpeakAndLine.py`)
- Serial polling loop → ThingSpeak sender: calls sender (evidence: `ProjectsArduino/Odroid_Project/odroidToThingSpeakAndLine.py`)
- Serial polling loop → LINE notifier: calls notifier (evidence: `ProjectsArduino/Odroid_Project/odroidToThingSpeakAndLine.py`)
- ThingSpeak sender → ThingSpeak: posts PM2.5 (evidence: `ProjectsArduino/Odroid_Project/odroidToThingSpeakAndLine.py`)
- LINE notifier → LINE Notify: posts alert (evidence: `ProjectsArduino/Odroid_Project/odroidToThingSpeakAndLine.py`)
