LED lighting system for plastic UFO model using Arduino :: Student Project

Do aliens use Arduino?

OK, maybe not…but a great way to create a fading eerie glow for a UFO model is an Arduino Nano and a handful of LEDs!

This neat and simple project was submitted by Stephen Dearden, a customer of  Programming Electronics Academy.

I totally saw this above my house last night…

Why did you build an LED lighting system for your plastic UFO model?

Besides electronics, one of my other hobbies is building model kits.

With LEDs and LED strips getting smaller and smaller, some model makers are now incorporating lighting into their kits.

I wanted to start simple and chose a popular model kit: the Area 51 UFO model from Pegasus Models.

How does your project work?

As you can see from the pictures and videos, the Arduino Nano controls the fade in/fade out behavior of six 3mm high intensity green LEDs.

The UFOs windows are green polystyrene and the whole effect gives it an eerie appeal!

What was your biggest struggle as you worked through this project?

Getting the code to work. Although a simple program, I am NO coder!

Did the project end up as you expected?

Exactly as I wanted it to be, although the connections from the Nano board to some stripboard containing the resistors turned out to be very “fiddly” in what was a confined space.

Looking back on this project, what can you say you have learned about programming and/or electronics through the creation process?

I have already some experience with electronics. My challenge was learning the programming.
