LED Hula Hoops


Hula hoops are fun treats for kids, after all these years, they still seem to attract attention. If you have one, you can update it with our latest LED tech hula hoop, which will give your kids a miniature light show while they play.

Twenty-one LEDs are used in this hoop; 6 are flashing LEDs that cycle through the colors of the rainbow. Each light is combined with a resistor and then wired together in a classic and simple parallel circuit. The battery for this project can be a laptop battery like the one used here, or a few AAA batteries taped into series. Either way, the tube can be taken apart for the battery to be easily changed.

Have fun with this funky colorful LED fashion gadget made especially for kids and all around it’s not a bad Sunday afternoon project.
