What is the basic principle used in potentiometer?
The basic principle of the potentiometer is that the potential drop across any section of the wire will be directly proportional to the length of the wire, provided the wire is of the uniform cross-sectional area and a uniform current flows through the wire.
How are potentiometers wired?
Normally, potentiometers are wired as variable voltage dividers: connect +V to one side, connect the other side to ground, and the middle pin will output a voltage between 0 and +V (fig 2).
How does a 3 wire potentiometer work?
To use the potentiometer as a voltage divider, all the three pins are connected. One of the outer pins is connected to the GND, the other to Vcc and the middle pin is the voltage output. What is this? Basically, the voltage divider is used to turn a large voltage into a smaller one.
How to program digital potentiometer?
How to Program The digital Pot IC. The INC , U/D and CS inputs manage the movements of the wiper together with the resistor array. With CS fixed LOW the unit is selected and activated to react to the U/D and INC inputs. HIGH to LOW transitions on INC goes through a a five bit incrementing or decrementing counter sequence (based upon on the
