Question

What is the delay time used in the program? (i.e., how long in seconds does the value of the pulsewidth remain constant before incrementing or decrementing?)

Answer 1

We know that delay() function syntax is void delay(unsigned int milliseconds), It takes input as miliseconds

Your Code :

Line 11
delTime = 50 [means delTime is initialised to 50]


Line 45
delay(delTime) ---> Introduces a delay of 50 milliseconds


Hence in the program delay time used is 50 milliseconds

Thanks, PLEASE COMMENT if there is any concern. Let me know if you need more details/information
