How to Use a Potentiometer With Arduino

Welcome to ERL Engineering! In today's tutorial, we're diving into the exciting world of Arduino and potentiometers to create a real-time clock pulse modulation project. By the end of this video, you'll have a clear understanding of how to vary the delay time of clock pulses using a simple setup.

5k or 10k potentiometer

LED for testing the output

Arduino board

Breadboard

Connecting wires

Begin by placing the potentiometer onto the breadboard.

Connect three wires to the potentiometer using the breadboard.

Connect pin 1 and pin 3 of the potentiometer to the +5V and GND pins on the Arduino.

Connect the center pin (pin 2) of the potentiometer to the analog A0 pin on the Arduino.

Connect an LED to pin 13 and GND on the Arduino for testing the output.

Coding Process:

In the video, we guide you through the coding process step by step. The code is crucial for this project as it controls the interaction between the potentiometer and the Arduino, allowing you to vary the delay time of clock pulses. Be sure to check out the video for a detailed explanation of the code.

The coding for this project is shown in the video where you will learn how to prepare the code of the Arduino UNO and upload it to your Arduino device.

After assembling the hardware and uploading the code to the Arduino, it's time to put our project to the test. Watch as we demonstrate the real-time modulation of clock pulses using the potentiometer. The LED connected to pin 13 serves as a visual indicator of the changing delay time.

In conclusion, this project provides a hands-on experience in combining hardware and software elements to create a dynamic clock pulse modulation system. Whether you're a beginner or an experienced enthusiast, this tutorial offers valuable insights into Arduino programming and potentiometer usage.
