In the Embedded track at TDC Florianópolis 2017, I gave a talk showing how to create connected hardware prototypes using NodeMCU and Firebase.

The goal was to demonstrate a fast and functional way to build IoT systems that communicate through the cloud without requiring a custom backend.

Covered in the talk:

  • Basics of NodeMCU and Lua firmware
  • Integrating with Firebase’s Realtime Database
  • Sending and receiving live data over Wi-Fi
  • Using Firebase as a lightweight communication layer
  • Tips on reducing complexity when prototyping connected devices

This was a practical talk targeted at developers who want to test ideas quickly using accessible and low-cost hardware.
