ESP8266 wifi shield for Arduino Robot Car and Internet of Things Learning Kit
This is a Wifi/Bluetooth extension Shield for Arduino which widely used for Wifi and Bluetooth Control in Arduino related projects.
This ESP8266 Arduino Wifi Shield connects Arduino Board to other remote devices through wifi Internet, a perfect IoT tool for Arduino fans.
The shield can work in two modes:
STA mode which makes your Arduino become an Internet node through router
AP mode which make your Arduino a Wifi Hotspot
ESP8266 wifi chip communicate with Arduino through serial port (both hardware serial and software serial).
Here are some sample projects on how to program and use this wifi shield through HTTP, MQTT and UDP protocols:
The shield'sESP8266 chip communicate Arduino UNO board through either Hardware serial or software serial. Easy to program.
The shield also has a Bluetooth Slot which can connect the popular HC02,HC05,HC06.. Bluetooth modules to Arduino Serial Ports. It also supports both Hardware Serial and Software Serial.
