@Christopher Stapels It is creating unneccesary DELAY for displaying ouput on my Display and also there is not much time in 1st and 2nd input

Can you describe your project? What are you tring to do? What is the desired result?
I see you have a thingSpeakWrite in the setup and the loop. I dont see any delay betweeen them. If you have the button depressed on startup, that could created too frequent of write calls. Are you using the free license? if so, you would have to wait 15 seconds after startup to press the button, and 15 seconds between each bitton press.
