Saatvik a bright and curious learner, loved working with circuits and light. One day, he came across an interesting idea—what if he could create his own colors using just a few components? That spark of curiosity led to his project: RGB LED Color Mixing using Potentiometers.
An RGB LED is a special kind of LED that combines red, green, and blue light. By adjusting the brightness of each color, you can make thousands of different shades. Saatvik decided to control each color with a potentiometer, a device that changes resistance and controls voltage in a circuit.
He gathered his materials: a breadboard, an RGB LED, three potentiometers, three resistors, and connecting wires. Carefully, he connected the RGB LED to the breadboard. Then, he added resistors to limit the voltage and wired each color channel—red, green, and blue—to its own potentiometer.
Next, he connected the terminals of the potentiometers to the positive and negative power rails on the breadboard. Once everything was in place, he powered the circuit.
As he turned each potentiometer, something amazing happened: the colors changed! Turning the red knob gave him many shades of red. The green one brought out bright greens and soft teals. The blue dial created cool blues and purples. By combining them, he made magenta, cyan, yellow, white, and countless other shades.
“This project was fun,” Saatvik smiled, “because I could see how voltage and resistance control brightness, and how color mixing works.”
Through his experiment, Saatvik didn’t just light up an LED—he lit up his imagination and learned how science, circuits, and creativity come together in amazing ways.
