hello to all
I want to generate a square wave using 555(in astable or monostable mode) in a manner that when an input(low) occurs
it should generate square wave for a period with ON time 1s and OFF time in the range of milli seconds continuously.This
square wave must continue generating whenever the input low is present and stop whenever the input is high.
plz suggest any easy methods.
