UNO and ESP8266

Hi all.

First post here.
I really need some help.
I have a UNO and a WiFi ESP 8266
How do i connect to an AP and send/receive data ?

Hope for help to get started on this one......
I cant believe how difficult it is to get connected.

Best Regards

Google is your friend...

1. Build the following connection (Fig-1) between ESP8266/NodeMCU and UNO using soft UART Port (SUART).

2. Write sketch for both Sender (the ESP) and Receiver (the UNO) so that message "Arduino" will be sent by ESP, and it will be displayed on SM2 of UNO.
