I ordered 5 ESP8266-01 microcontrollers and a programmer kit for controlling my signals. This version of the WIFI controller has 2 GPIO’s, which perfectly fits to control 2 LED’s – a green and a red one.
After digging thru Google, I finally got the Arduino IDE plus ESP8266 plugin. Yesterday I tried some experiments and – tah dah – It is working as webserver…..
Now I’m on to implement a web interface to control the signal. More to come
