DIY Lightsaber Circuit

Bring STEAM learning into your home with this simple DIY Lightsaber Circuit activity that your kids will love!


  • CR2032 coin cell battery
  • A two Prong LED (light-emitting diode)
  • A colored Straw
  • Tape

How to build your Lightsaber Circuit:

  1. Build a circuit by connecting the LED the coin cell battery. 
  2. Hack a Lightsaber by holding the LED and battery together with tape.
  3. Cut a straw in half, and slide it over the LED
  4. Ta-daa! You have made a Lightsaber Circuit! 

How Circuits works:

An electric circuit is like a pathway made of wires that electrons can flow through. 

A battery or other power source gives the force (voltage) that push the electrons through the circuit.  This is called electrical current.

When the electrons get to a device like a light bulb, your computer, a refrigerator, or even an LED they give it the power to make it work!

The word “circuit” sounds like “circle,” and a circuit needs to be circular to work. The wires have to go from the power source to the device and back again, so that the electrons can go out and come back.

Microcontroller Specs 

The Zubi Flyer is the bomb dot com for makers: 5 PWM pins, 12 DIOs as well as hardware serial connections Rx and Tx. Running at 16MHz and 5V. The onboard switch-mode boost regulator is designed to operate on 3 Volts.  Power can be supplied from a 3 Volt CR123A battery or from a USB cable that provides regulated +5 Volts DC to the board. Do not run any power exceeding 5 Volts as the regulator cannot handle step-down voltage.
