Hi Ahmad Great In previous programs, you used delay (); command . In this program, you used the waitForResponse (); function. Would you explain this difference?

Arduino do nothing while in delay time. so, to increase the performance of the program I have used waitForResponse() function without using any delay(). But this function is under development. I am working on it to make the code more efficient.
