DIY: Wired LEDs & RGB LEDs




About: Youtube:

In this tutorial, I will be showing you how to make your own wired LEDs for Arduino using jumper wires.


5mm RGB LEDs:

5mm LEDs:

M-F jumper wires:

Additional components:

Heat gun:

shrink tube:

Wire stripper:


Step 1: LED Wiring

Cut all the led pins by half and connect the jumper wires according to the matching colors. same goes for regular LEDs.

Step 2: Shrink!

Cover the LEDs using shrink tube and use the heatgun to shrink it. Use a smaller shrink tube for the non-RGB LEDs as it only has two pins.

Step 3: Done

    I have a sort of Mystery. I took apart a butterfly color changing toy, And inside there were two button cells, a small switch, and an RGB that was about twice as wide as a normal LED. I was confused, because I thought that since the LED switched colors in a certain slightly-long sequence, It should have a small circuit board that controls the changing colors. I plugged the LED (Just the LED) up to two AA batteries, and it started shining in that sequence. Do you know how it can do that?

    Yes, There are different types of LEDs out there

    Some LEDs can flicker like candles while other LEDs can change colors without a circuit board.

    Thanks, that's interesting! I found a hat that had a bunch of optic cables in the form of a smiley face, so I took 3 AAA batteries, made a battery pack out of them, put a switch on it, taped the LED to the end of the optic cables, and wore it to camp.

    What do you use for lightning, background and camera when taking your shots?
