Introduction

For this week assignment, we had to create a Graphic User Interface (GUI) by implementing design and programming protocols. I decided to use the ESP8266 NodeMCU board

Below shown the steps I did to connect the ESP to the internet and test it.
To test the ESP8266 I have generated an LED_WIFI code, where I connected the ESP to the internet and control the LED ON/OFF using my phone. The method to control the LED, was to generate a simple Web User Interface with a simple ON and OFF buttons

STEP 1: PIN connection

The connection was as the following
- Pin D6 ------> +LED
- GND ------> -LED


STEP 2: Installing NodeMCU Library

This step is to install the ESP8266 package as the following
- Open up Arduino IDE. Go to Files-> Preferences. Enter
- Go to Tools--->Boards--->Board Manager, search for ESP8266 and install the package.




STEP 3: Start Programming

In the below figure, shown the steps of initiating the program of NodeMCU. It is important to add the package installed in step 2 as well as incerting the Wifi User Name and Passcode

Problems faced

The main problem that was facing was to connect the ESP to the internet. I was always reciveing an error while connecting. after several trials, I figured that I had an issue with the library and the connection. So problem was solved.
