My best guess at this time is the ESP32 on a development board, but it really depends on what you already have experience with, and what is easy to get for you.

Depending on the LED.

A simple LED can run with just a resistor. Each LED has a maximum current, and it is easiest to add a resistor so the LED cannot draw more than this current.

If you have a higher power LED (I had a 1W LED in the eye at the time) you might want a LED driver, because it is way ...

The list on there is basic, and the project is already old, so it is a bit challenging to even note what your would specifically need and not need. Roughly, the white LEDs, led driver and 40mm fans are for the light. The rest is for the moving part.

Note that the page here and on instructables is ...

Thank you,
