As according to my knowledge I should use one "counter" and "compare" its output with 100 and gets the pulse high when there is a flow of 1 ltr completes. Tell me how to put counter output into comparator.How to use RAM memory? and how to compare it ,as I cant find any COMPARATOR in logo...please help me out
