the code of wifi control car didnt work, i use e-gizmo328, wifi shield CC3000 and servo motor. It already connected in the wifi but when requesting an IP address its stock.

Pin CONNECTION

MISO = pin 12
MOSI = ping 11
SCK = pin 13
CS = pin 10
IRQ = pin 3
V-EN = pin 5

THIS IS THE CODE!!

    HELP ME GUYS PLS!!!!!!!!!!!!!!!!

THIS IS THE CODE!!

But I am not going put it in code tags to stop the forum software mangling it despite the advice given in Read this before posting a programming question ...
