P5.js with ESP8266 WiFi

Processing for Pi
12

I succeeded, only one sketch to upload to esp8266 with arduino code and P5js code, it works and is bidirectional.
thanks to jafal for the links and RichardDL, if you want try it maybe the Rasp… clicking inside the circle the led turns on, clicking outside the circle the led turns off. it needs to be improved
