1. Stack ESPWiFi Shield onto compatible Arduino Board. For this example, Arduino          
Unoisused.
2. Select USB for both RX and TX pins. **Note: This setting is only for entering AT               
command.

4. **Note: For AT Test, connect RST pin to GND using jumper wire. (Another            
alternative, upload an empty sketch to Arduino main board before stacking          
