Project README

Overview

This project consists of two Arduino sketches for distance measurement using an ultrasonic sensor, with data communication facilitated through AWS IoT and Arduino IoT Cloud. The main.ino sketch is designed for AWS IoT, while the Untitled_mar02a.ino sketch is tailored for Arduino IoT Cloud.

AWS IoT (main.ino)

The AWS IoT sketch connects an ESP8266 to WiFi, synchronizes time using NTP, and publishes distance data to AWS IoT using MQTT. The distance is measured by an ultrasonic sensor (HC-SR04), and the AWS IoT platform is utilized for remote monitoring.

Arduino IoT Cloud (Untitled_mar02a.ino)

The Arduino IoT Cloud sketch employs an ultrasonic sensor to measure distance, controlling an LED based on the measured distance. Additionally, it communicates with the Arduino IoT Cloud to update variables such as ultraSonic, led, and message. The sketch includes functions generated by the Arduino IoT Cloud Thing for handling variable changes from the IoT Cloud Dashboard.

Prerequisites

AWS IoT (main.ino)

1. Arduino IDE with ESP8266 board support.
2. Required libraries: ESP8266WiFi, WiFiClientSecure, PubSubClient, ArduinoJson.
3. AWS IoT account with endpoint, certificates, and Thing Name configured.

Arduino IoT Cloud (Untitled_mar02a.ino)

1. Arduino board compatible with Arduino IoT Cloud.
2. Arduino IoT Cloud account - Arduino IoT Cloud.
3. Required libraries installed using the Arduino Library Manager.

Hardware Setup

AWS IoT (main.ino)

Arduino IoT Cloud (Untitled_mar02a.ino)

Connect the ultrasonic sensor and LED according to the specified pins in the sketch.

Configuration

AWS IoT (main.ino)

1. Modify the secrets.h file with WiFi credentials, AWS IoT endpoint, and certificates.
2. Adjust time zone, ultrasonic sensor pins, and MQTT topics as needed in main.ino.

Arduino IoT Cloud (Untitled_mar02a.ino)

1. Open the thingProperties.h file and update it with your IoT Cloud credentials and Thing properties.
2. Set up the Arduino IoT Cloud Dashboard with widgets for message, ultraSonic, and led variables.

Usage

1. Upload the respective sketch to your Arduino or ESP8266 board.
2. Monitor the serial output for debugging information.
3. Use the IoT Cloud Dashboards for AWS IoT and Arduino IoT Cloud to interact with variables and observe real-time changes.
