	replace pin number by a variable - changing pin is much less tedious and cumbersome.		replace pin number by a variable - changing the pin is much less tedious and cumbersome.
	~~replace~~ delay by a variable - ~~doesn't seem useful first~~. ~~but:~~		replacing the delay by a variable - only change it once.

	Changing variables during runtime (while the program is running) is also possible:		Changing variables during runtime (while the program is running) is also possible:

			'''Most simple example of changing a variable:'''

			<source lang="c">
