Potentiometer Variable Resistor

The Potentiometer Variable Resistor project demonstrates how to read analog values from a potentiometer using an Arduino Mega. Potentiometers are variable resistors that allow for manual adjustment of resistance by turning a knob.

Components Needed

• Arduino Mega
• Potentiometer
• Jumper Wires
• Breadboard
• Power Supply

Block Diagram

Circuit Setup

Connect the Potentiometer to Arduino Mega:

Instructions

Circuit Setup:

onnect the potentiometer to the Arduino Mega as per the circuit setup section.

Library or Dependencies:

No additional libraries are required for basic analog input reading.

Code Upload:

Open the Arduino IDE and create a new sketch.

Copy and paste the provided Arduino code into the sketch.

Upload the code to the Arduino Mega.

Testing:

Open the Serial Monitor in the Arduino IDE (set to 9600 baud) to monitor the potentiometer values.

Rotate the potentiometer knob and observe changes in the displayed analog values.

Applications

Notes

Ensure the potentiometer is securely connected to provide stable analog readings.

Experiment with different potentiometer types (linear or logarithmic) based on project requirements.

Consider integrating potentiometer readings with other components for dynamic control.
