Hi Reeshma,

I suggest the following:

1. Install Arduino IDE
2. Get blink.ino example working.
3. Get another example (that shows how to read digital input) working.

At this point you should be able to write a program doing what you described.

Many would prefer to avoid arduino IDE.
@dotthree, Instead of Arduino IDE you can use esp-idf and program in plain C and/or C++.
I personally would really love to see a comprehensive GPIO example which shows multiple pins set up and working simultaneously.
Esp-idf provides example with four GIPO pins set up and working simultaneously.

What exactly is your requirement ? I suggest you to go through basics of freeRTOS : Task, Queue, Semaphore. They would help you understand examples in esp-idf better. Also go through the readme files in each example folder.
