Potentiometer is used to manually adjust values like volume and brightness. Potentiometer has GND, VCC, and output pins. Shaft rotates from 0° to ANGLE_MAX (manufacturer-dependent). Output voltage varies directly with shaft rotation angle
Required components include Arduino board, LED, potentiometer, 220 Ohm resistor. Common ground connection established between Arduino GND and breadboard. LED connected to PWM-compatible digital pin (3-11). Potentiometer connected to analog pin A1
Potentiometers control electrical current movement through adjustable wiper. Constructed from carbon, conductive plastic, or wire-wound materials. Used in audio, motors, and instrumentation systems
Potentiometer is a variable resistor with three terminals for current control. Resistor regulates electric current flow in circuits. LED connects to Arduino via digital pin 10 and 220 Ohm resistor
Resistors can be connected in series, parallel or combinations. Series connection means resistors are daisy chained together. Current flows through all resistors in series. Total resistance equals sum of individual resistances
