LED Ring Around The ESP8266. 10 Comments . by: Richard Baguley. September 12, 2015. Title: ... including the Gerber files for the board and the Arduino code that the ESP8266 is running.

As usual I’ll be using a NodeMCU board (I really did order a lot of them) which uses an ESP8266, but there’s no reason this would be difficult to achieve on an Arduino-based device.
