Arduino WiFi
Add WiFi(ESP8266) to Arduino UNO
If ESP-01 Adapter is used, Connect VCC=5V.
If ESP9266 module is used, Connect VCC=3.3V
Arduino sketch code
First use UNO-PC Serial Baud 9600, UNO-ESP Serial Baud 115200
In Serial Monitor (Baud 9600) : Type
Now, we have changed ESP8266 Serial to 9600.
Modify the Arduino Sketch to ESPserial.begin(115200);
and upload again.
