I need some help

I am trying to build a replica Alpha 5 helmet from Mighty Morphin Power Rangers. I have the thing built, now i need to install some sequenced LEDs into the visor, the problem is, I know nothing about programming LEDs. Can someone point me in the right direction?

Use a microcontroller.

The most popular option right now is to use an Arduino.

Buy extra LEDs. That way, if you let the magic smoke out by supplying too much voltage, you’ll have a learning experience rather than an extra trip to your electronics store.
