Note: This repository version involves wifi networking. For the static (non-networking) version of this project, please see the /defang-arduino-static repository here.

This repository contains an interactive wifi-connected UI program for a SenseCAP Indicator Device, built for an Embedded Systems project at Defang Software Labs.

The device has a square liquid-crystal touch screen display, and a ESP32-S3 chip that can be programmed in an Arduino environment.

The program welcome.ino, acting as a client, pings data every 5 seconds after it is connected to a wifi network. It uses a library called ArduinoHTTPClient. It is also recommended to use Arduino IDE when coding with .ino files. The program UI will display a message that is randomized in color and location on the screen at the same time during pings (every 5 seconds).

The Flask server in web_server.py receives these pings when it is initialized and connected to the same wifi network as the client. To initalize it, run python web_server.py. To view it, open localhost with the port number used. To deploy it to the cloud, run defang up in the \welcome directory.

A helpful file called serial_reader.py decodes serial monitor readings to a readable format, allowing you to see Serial.println() messages in real time when running. To initalize it, run python serial_reader.py and see it show up in the terminal.
