Because the Arduino's microcontroller can move fairly quickly, at least relative to what we can perceive, it is often necessary to make use of various delays to slow things down. We have already briefly mentioned some of the functions and techniques used for slowing things down, but this section will go into them in greater detail and provide some examples of why you might look at other methods for creating a delay beyond the standard Arduino functions.
From the very beginning with our first Blink sketch, we have made use of the
delay() function to create a short pause in the middle of a program. There's really not a whole lot to the function, but there are some things we need to be aware of. The syntax for the function ...
