Introduction: Glow Circuit Assembly

In this tutorial, you'll learn how to make your design light up using the Glow Circuit Assembly, which combines a light emitting diode (LED) and a coin cell battery.

Let's get started!

Step 1: Gathering Your Parts

You'll need two electronic components:

  1. An LED
  2. A 3V Coin Cell Battery (CR2032)

Find all Glow components on Sparkfun

You will be leaving Tinkercad and taken to an external site when you click the link above.

  1. Gather all your electronic components as well as your 3D printed Glow holder
  2. Continue to the next step.

Step 2: Add the Coin Cell Battery

  1. Align the positive side of the battery (labelled "+") with the “+” indicator on the holder.
  2. Continue to the next step.

Step 3: Add the LED

  1. Insert the LED from the top, making sure that the longer leg lines up with the “+” indicator on the holder.
  2. Continue to the next step.

Step 4: Glow!

Your LED should now light up!

If it is not lighting up, make sure that your battery and LED are inserted in the correct direction aligned with the “+” on the holder.

To turn off your glow assembly, remove the LED.

Congratulations, you’ve built the Glow Circuit Assembly!
