ESP32 Universal Robot

This project involves firmware for an ESP32 connected to an 8-channel relay module. The relay module is utilized to control a Universal Robot as a digital input.

🌟 Features

• Firmware built with Arduino and PlatformIO
• Web Application built with React and attached to ESP32
• API for controlling the relays

🚀 Getting Started

Prerequisites

• PlatformIO
• Node.js

Installation

1. Clone the repository

   git clone

2. Create a new file named secret.h in the src folder and add the following code:

    #pragma once
   
    #define WIFI_SSID "YOUR_WIFI_SSID"
    #define WIFI_PASSWORD "YOUR_WIFI_PASSWORD"

3. Build and upload the firmware to the ESP32

   pio run -t upload

4. Build and upload web interface to ESP32 filesystem image

   pio run -t uploadfs

   Dependecies for web interface are installed automatically by PlatformIO when you build filesytem image. For more information about script, check script folder.

📝 Documentation

API

• GET /ip - Get the IP address of the ESP32
• GET /status - Get the status all of the relays
• POST /relay/:id - Set the state of the relay with the specified ID
  • Content-Type: application/x-www-form-urlencoded
  • Body: state ("on" or "off")
• POST /relay/all - Set state of all relays at once
  • Content-Type: application/x-www-form-urlencoded
  • Bodu: states ["on", "off", "on", "off", "on", "off", "on", "off"] --> just example

✅ To-Do

• Fix indexing mistake between the UI and the actual relay id
• Make it using websocket, so the page doesn't need to be refreshed to display real-time relay condition
