Pin Configuration

Component Overview:
The 10K 16mm Rotary Pot (Pack of 5) is a type of potentiometer that is commonly used in various IoT projects, such as robotics, automation, and sensor applications. It is a rotational potentiometer that provides a 10k linear output resistance, which can be used to detect rotational angles or positions.
Pinouts:
The 10K 16mm Rotary Pot has three pins, which are connected as follows:
Pin 1:
Terminal: CCW (Counter-ClockWise)
Function: This pin is connected to one end of the 10k resistive track.
Description: When the potentiometer is rotated counter-clockwise, the resistance between Pin 1 and Pin 3 increases, while the resistance between Pin 1 and Pin 2 decreases.
Pin 2:
Terminal: Wiper
Function: This pin is connected to the wiper (moving contact) of the potentiometer.
Description: The wiper moves along the resistive track as the potentiometer is rotated. The voltage at Pin 2 varies linearly with the rotational angle, making it an output pin.
Pin 3:
Terminal: CW (ClockWise)
Function: This pin is connected to the other end of the 10k resistive track.
Description: When the potentiometer is rotated clockwise, the resistance between Pin 3 and Pin 2 increases, while the resistance between Pin 3 and Pin 1 decreases.
Connection Structure:
To connect the pins of the 10K 16mm Rotary Pot, follow these steps:
Connect Pin 1 (CCW) to a stable voltage source (VCC) or a fixed voltage reference.
Connect Pin 2 (Wiper) to an analog input pin of a microcontroller or an analog-to-digital converter (ADC).
Connect Pin 3 (CW) to a stable ground (GND) or a fixed voltage reference.

By connecting the pins as described above, you can read the rotational angle or position of the potentiometer using an analog input pin of a microcontroller or an ADC. The output voltage at Pin 2 will vary linearly with the rotational angle, allowing you to detect changes in the potentiometer's position.
