Arduino Tinkercad Project #8: RGB LED Brightness Control with Potentiometer & Button
Welcome to the eighth installment of our Arduino Tinkercad Projects series! In this video, we delve into an intermediate-level project where we control the brightness of an RGB LED using a single potentiometer and a push-button. This setup allows you to adjust the intensity of red, green, and blue channels individually, enabling the creation of custom colors through additive mixing.
Utilizing Tinkercad Circuits, a free online simulator, we demonstrate how to implement this project without the need for physical components. This is perfect for computer programmers and tech enthusiasts who are eager to learn but may have budget constraints.
The project incorporates essential concepts such as analog input reading, PWM signal generation, and state management using a button to cycle through color channels. By the end of this tutorial, you'll have a solid understanding of how to manipulate RGB LEDs and create dynamic lighting effects.
What You'll Learn:
How to read analog values from a potentiometer to control LED brightness.
Implementing PWM (Pulse Width Modulation) to adjust LED intensity.
Using a push-button to cycle through RGB color channels.
Managing state changes and debouncing button inputs.
Creating custom colors by mixing different intensities of red, green, and blue.
Simulating and testing your circuit using Tinkercad Circuits.
