NodeMCU is an open hardware IoT platform based on eLua for the ESP8266 microcontroller. It allows creating low-cost projects using Wi-Fi and easy scripting in Lua, which makes it great for making wearables, for example. In this talk I'll give an introduction to the platform, show how I built an audio reactive graduation dress and share the materials to get you started on your own wearable project. This talk is ideal for beginners to hardware hacking or Lua enthusiasts looking for project inspiration.
