Build an "Autobot Notification System" with ESP8266 and Lua
Getting your project connected to the Internet is easy and has never been so inexpensive thanks to the rise of the ESP8266-based NodeMCU development boards - and one example of this has been demonstrated by Instructables member pjtheman:
After finding an piece of Transformers memorabilia, it was fitted with a bar of WS2812B RGB LEDs (aka "NeoPixels") that are controlled by the NodeMCU board. This can now be illuminated on command via WiFi through the NodeMCU board:
Notifications are generated by events using the IFTT (If This, Then That) cloud-based service - or you could directly contact the NodeMCU unit using other means.
Either way, this is an interesting example of controlling a NodeMCU board form afar - so to learn more and examine the code - visit the project's Instructable page.
