Hello, after using the help of the members of this forum I have succed to control
two engine with wifi card (arduino wifi shield http://arduino.cc/en/Main/ArduinoWiFiShield) and
the motor card (arduino motor shield http://www.instructables.com/id/Arduino-Motor-Shield-Tutorial/?ALLSTEPS) but the problem in pin 9 since it is reserved for wifi card so it presents an error
who can help me ,for exemple I can change the motor 2 to
work with another pin or anything, I need your help
this is my arduino code
#include <SPI.h>
#include <WiFi.h>
char ssid[] = "mon reseau wifi"; // your network SSID (name)
char pass[] = "mon mot de passe"; // your network password
int keyIndex = 0; // your network key Index number (needed only for WEP)
