A way to make simple digital potentiometer Circuit Diagram A digital potentiometer is an essential component in the circuit of any electronic device. It's a variable resistor that can be used to control the voltage and current of a circuit. In this article, we'll discuss the importance of digital potentiometers and how they're used in circuit diagrams.
A digital potentiometer serves the same function as a potentiometer in hardware in that it varies resistance output. The difference is a digital potentiometer IC is controlled by software, while a regular potentiometer is controlled manually by a person. Just like a regular potentiometer, a digital Pot IC comes in all different values of The digital potentiometer (digipot) is a processor-controlled, • The required resistance value, often called end-to-end resistance, is determined by the design considerations of the circuit. Vendors offer resistances between 5 kilohms (kΩ) and 100 kΩ in a 1/2/5 sequence with some other intermediate values.

the digital potentiometer. RAB is the nominal resistance across the entire potentiometer, from pin A to pin B. RBW is the resistance between pin B and pin W of the digital potentiometer. n is the number of digital potentiometer bits. For the MCP4XXXX family of potentiometers, the number of bits is eight. Dn is the digital code in decimal form A potentiometer is a variable resistor that can be used in a circuit to control resistance, current, and voltage through a circuit to attain a certain output, we already know the basics of Resistor and how they work. The potentiometer is just a variable resistor, sometimes also called a rheostat, which you all could have seen in your physics laboratory, it consists of a metal coil wound on a The typical potentiometer will have 3 pins, two power supply pins (+5V and GND), and one pin that connects to an analog input pin on your Arduino to read the value output. To learn how to read data from a potentiometer, and display it in the Serial Monitor, visit the Analog Read Serial example. Hardware Required. Arduino board; Potentiometer
It also makes the circuit diagram a little bit nicer-looking I think. Wiring Example #3: Potentiometer as Volume Control. This example uses all three pins of the potentiometer to create a simple way of adjusting the volume of an audio amplifier.

In this second design we investigate the IC X9315 which is actually a solid state digital potentiometer and could be used exactly like a mechanical potentiometer, but through logical supply inputs. The IC X9315 from Intersil, is a digitally controlled solid state potentiometer, which internally possesses an array of resistors, wiper switches, a
