Hi all,
I am currently doing a project that involves a 74ls74ap, which is a dual d type flip-flop. The set and reset of the 2 d flip-flops are at +5v. Both flip-flops have the same clock frequency.
A push button is connected to the input of D1. Output Q1 is connected to a AND gate input and input D2. Output D2bar is connected to the same AND gate and the AND gate output should output a "high" whenever the push button is pressed. So basically, this is a single pulse circuit design.
Now the problem here is, even though I didn't press the push button, Q1 is always at logic high, making the output of the AND gate always at logic low.
Is there anyway to make the output of Q1 low and go high only when I press the push button?
