Arduino is an opensource physical computing platform based on a simple I/O board and a              
development environment that implements the Processing/Wiring language. ESPWiFi Shield        
can be used together with Arduino Uno. Figure below shows example hardware connection            
between Arduino Uno and ESPWiFi Shield; it is simply stacking up the shield onto the              

2. Please be cautious to initialize the correct Arduino’s digital pin in coding/software           
according to the selected TX and RX pins for the communication. We recommend            
