5. Connect Arduino board to PC using USB cable.
6. Open Arduino IDE. Determine which COM port Arduino Uno is connected to and
configure the port settings under menu Tools > Port.
7. Go to File > Examples > CytronWiFiShield and open example sketch
CytronWiFiDemo.
8. Change ssid from “...” to your network name and “pass” to corresponding password.
For example, your network router SSID is WiFly and password is abcd.

configuration is correct.
10. Upload the program to Arduino board.
11. Open Arduino Serial Monitor to view the progress. Setup to 9600 baud.
12. Make sure PC is connected to the same internet network with the ESPWiFi Shield.
