Class 29 | Iron Man Rainbow Arc Reactor | Arduino RGB LED Pulse Effect
In Class 29, we bring Iron Man’s Arc Reactor to life using an Arduino and an RGB LED.
Watch the reactor pulse like flowing energy, glowing repeatedly and then resting — just like a real power core.
This beginner-friendly project teaches loops, delays, timing control, and how to create realistic lighting effects for robotics and cosplay projects.
📖 Iron Man Says:
“Watch the power of my arc reactor change colors like a rainbow pulse!”
