Arduino RGB Color Mixer With LEGO Enclosure and Bead Crystals

This machine allows users to transition between different colors by rotating a knob connected to an Arduino-controlled RGB LED.

Electronics:

Arduino Uno Board - 1 pcs

RGB LED - 1 pcs

Potentiometer (10kΩ) - 1 pcs

Resistor 220 Ohm - 3 pcs

Jumper wires - 8 pcs

USB cable - 1 pcs

Power bank - 1 pcs

LEGO pieces for enclosure

Beads for decoration

Legs of RGB led are connected to PWM pins on Arduino UNO board through resistors.

The potentiometer sends values from 0 to 1023, which are then mapped into smooth transitions using code.

I built a custom LEGO enclosure for this project from my rocket LEGO I have built before.

Image of the rocket is attached as well.

Colorful beads were added to act as crystal-like elements.

The circuit is placed inside LEGO enclosure, and beads are scattered around.

The final version demonstrates a working RGB color mixer controlled by potentiometer.
