问题


I'm trying to control 8 channel relay with esp8266. and i've been following this tutorial on youtube https://www.youtube.com/watch?v=dLmz0xdDOLk I did exactly what the guy said. I uploaded my code to Arduino and I get a "parseObject() failed" error on the serial monitor while the code trying to parse JSON i think(not sure). I don't really understand coding much so I wonder if you guys help me out with my project.(the only thing I couldn't do was to change my web host PHP version to 5.2, I use 5.3.29- obsolete)
