If you want light your model and you do not know how to do it, this may help you a little bit. I’ve never been good in electronics I could make my onw circuit board according to a drawing and solder parts on the board, but I never could invent something new or to program something precisely so that it would fulfills the required purpose. But there is a very simple way – Arduino.

What is Arduino?

Arduino is a programmable circuit, which for example on costs you $11 – Arduino nano v3. Board is equipped with 12 digital and 8 analog inputs / outputs that can be used for connecting any components – LEDs, motors and servos, switches and more. After connecting the USB cable, you can use a simple program on a computer to program the circuit according to your needs. To program is accurate and literal, because this is no graphical interface where you dragged the LEDs and tell them to flash. You really have to use programming. The advantage of course is that it is extremely simple and the program itself has a built-in examples that you can use. The biggest advantage is the wide base of users, lots of available codes and also a lot of modules that can be purchased for Arduino.

I bought some modules for one of my projects and some just for testing, these are microSD card reader, motion sensor, numeric display, potentiometers, servos, sensors, wireless charging and RGB LEDs. What for?


  1. MicroSD card reader can be used for example to build sound player which will play WAV audio files from SD Card. It can certainly have a wide range of applications, such as a sound effect in a variety of weapons, phaser, tricorder or even models.
  2. The motion sensor can be used for example for the light switch. I’m going to use it in replica of some consoles or similar Ancients equipment (Stargate), which are activated by wave of the hand over control crystals.
  3. The numeric display can be used to manufacture replicas of some explosives, which counts down the time. In my case, it will be a replica of antimatter charge of the series FRINGE (but I will not use the numeric display, instead will be used the Siemens SCDQ5581 dot matrix display).
  4. Potentiometers will be used for control, such as lights or servos. They can be purchased either as rotating or sliding elements.
  5. Servos are small motors which can be programmed to rotate in steps (degrees). It can help in many cases and can be used for example for opening the hangar doors, tilt the nacelles and other similar things.
  6. The sensors can be used for many things, I ordered ultrasonic distance meter. Ideal for experiments or the building of a functional Tricorder 😀
  7. Wireless charging is cool and you can use it everywhere where it fits and where we dont want to have the charging connector. The result can also look very impressive, you will have a stand in a nice design and all you need to do is just put your prop on the stand for automatical charging.
  8. RGB LED, usable for anything where you want to occasionally change color, such as electronic candle or lamp.
  9. Small batteries for Ipod Nano 6th. Suitable for models which can not hold large batteries.

In the videos below are some examples of circuits build by myself on breadboard. This is very useful for testing, you do not need to solder anything and you can flexibly change the components and wiring.

These are: Light imitating heartbeat; RGB color changing light; Player of wav files from SD card
