Hello all,
Simple question for you.
I am building a "generalized" astable 555 circuit where the two resistors and one capacitor that control the frequency and duty cycle are infinitely variable
(the capacitor is not infinitely variable, but can have 256 values).
I'm using potentiometers for the resistors.
But I can connect the potentiometers as variable resistors or voltage dividers.
So I'll ask you a general question:
In a digital circuit, when a potentiometer is used, should it be connected as a variable resistor, or as a voltage divider?
or
What are the pros and cons of a variable resistor vs a voltage divider in a digital circuit?
And I thank you in advance.
