Load Demo

Wifi Test

  • You can get the code from the Resources link.
  • Open Serial_Wifi.ino with Arduino IDE. Select Arduino Leonardo board and the USB port in Tools.
  • Modify the wifi information in the code.

#define SSID "TP-LINK_401"  // your ssid
#define PASS "20160704" //pass word

  • Upload the code.
  • Open the serial monitor to Check the wifi IP address.
  • Open the browser and visit the IP address. if you receive the "hello", the wifi test is successful.
