Introduction

The ExampleCode-AWiFi-with-Arduino repository is designed to help developers understand and implement WiFi-based IoT solutions using Arduino. Each example in this repository is crafted to demonstrate a specific use case, such as reading sensor data, controlling devices remotely, or displaying information on an OLED screen. The examples are easy to follow and can be used as a foundation for more complex projects.

Installation

To use the examples in this repository, follow these steps:

1. Clone the Repository:

   git clone https://github.com/Compassy/ExampleCode-AWiFi-with-Arduino.git
   

2. Open in Arduino IDE:

   • Open the Arduino IDE.
   • Navigate to File > Open... and select the .ino file from the desired example directory.

3. Install Required Libraries: Some examples may require additional libraries. Make sure to install them via the Arduino Library Manager (Sketch > Include Library > Manage Libraries...).

4. Upload to Your Device:

   • Connect your ESP8266/ESP32 module to your computer.
   • Select the correct board and port from Tools > Board and Tools > Port.
   • Click the upload button.

Examples

Sensor Integrations

• AWiFi_BH1750-OLED: Measures light intensity using the BH1750 sensor and displays it on an OLED screen while sending data over WiFi.
• AWiFi_DHT11OLED / AWiFi_DHT22OLED: Reads temperature and humidity data from DHT11/DHT22 sensors and displays it on an OLED display.
• AWiFi_HCSR04OLED: Measures distance using an ultrasonic sensor (HC-SR04) and shows it on an OLED screen.

WiFi Communication

• WIFI_CLIENT / WIFI_SERVER: Basic examples showing how to set up a WiFi client or server using the ESP8266/ESP32.
• WIFI_DIRECT_SERVER: Demonstrates setting up a WiFi Direct server for peer-to-peer communication.
• WIFI_SCAN: Scans available WiFi networks and displays the results.

Display Control

• AWiFi_AnalogOLED: Displays analog sensor values on an OLED screen while sending data over WiFi.
• AWiFi_TestOLED: General example for testing OLED display with WiFi functionality.

IoT Protocols (MQTT)

• MQTT_PUBLISHER / MQTT_SUBSCRIBER: Shows how to use MQTT for publishing and subscribing to topics, enabling real-time IoT communication.
