IoT Super Friday

This workshop involves programming ESP32 modules to take on different responsibilities as part of a larger network. We use PlatformIO as the development environment.

We assume you're using a Mac lappy with Brew installed.

You (or your pair) will need:

• An ESP32 module
• A laptop with a regular USB-A port (or USB-A dongle)
• Appropriate jumper cables and hardware for your project

Getting Started with PlatformIO

Install CP210x drivers for the ESP32 modules.

For the next steps, feel free to use either Visual Studio Code or CLion.

Using PlatformIO with Visual Studio Code

1. Install VS Code (if you don't already have it)

   brew cask install visual-studio-code

2. Install PlatformIO IDE (or search for the extension in VS Code)

   code --install-extension platformio.platformio-ide

3. Follow the PlatformIO VS Code Quick Start guide. When setting up a new project, use the following info:
   • Board: Espressif ESP32 Dev Module
   • Framework: Arduino
4. Once you have completed the steps in the Quick Start Guide, delete the contents of the file src/main.cpp and replace it with the code from our Hello World example.
5. Build the code with the ✓ icon and upload the code with the ➡ icon (both in the footer menu bar). You should now see a blue LED blinking on the ESP32 module.

Projects

Once you have the ESP32 module drivers installed and PlatformIO set up and ready, you can start with one of these projects.

• Motion Sensor
• Build Monitor
• Glowing Eyes
• Glowing Eyes Connected
• Remote toggle
