hi,
if I have a constant drip of water and i want to know exactly when each drop falls, so you can say the water is like a resistor and put two wires aligned exactly below the drop and when it falls it will trigger a 741 op amp circuit to make a line go high to 5V, so it can be detected by a PIC microprocessor.
so i have this sketch and its kinde works but not so good i wanted to know some advice about how to approach this to get it to work better, meaning what changes can be done in the circuit to adjust it to work better.
