Simple AWS IoT Application

A simple complete stack IoT application stack with a button and led iot devices. This uses ESP32-S2 boards as the iot thing platform, connecting to AWS using AWS IoT Core. Finally a hosted svelte front-end to access the status of the IoT devices

Prerequisites

• A stable WiFi connection
• An AWS account
• Basic soldering equipment and knowledge

Hardware

• For each IoT device (x2):

  • ESP32-S2 Device Specifically used the Adafruit QT Py ESP32-S2 WiFi Dev Board

    

  • Adafruit IoT Button with NeoPixel BFF Add-On for QT Py Soldered to the ESP32-S2 to add a button and NeoPixel functionality. The Adafruit QT Py ESP32-S2 already has these features but I have found that this add-on is far more user friendly. The LED is a larger diode and the button is far more tactile and fun to press

    

Steps

Step 1 - preparing the IoT devices

1. Solder the add-on board to the esp32-s2 Solder the add-On board using the provided header set. The add-on is soldered the the underside of the ESP32-S2. Ensure the add-on board is lined up to the right side in-line with the indicators on it.

2. Install the Arduino IDE 2 and setup the IoT devices. Follow the Adafruit QT Py ESP32-S2 guide to set the board up ready to upload firmware in the next steps. To ensure the add-on board is working you can use the Adafruit add-on guide to check. These page guides are saved in PDFs in the guides folder.

Your IoT devices should now be ready to have our firmware installed onto in further steps
