LEDs

LEDs are a simple, cheap, and fun programs for grades 3-adult.

We use LEDs to teach teens about  how they are used in the world around them and circuitry.

Tip- Many teens do not know how to hand sew so you’ll have to teach them how to tie a knot, how to do a running stitch, and how to close a stitch.

EASY – LED Origami ($100 for 20 teens)

Materials: Origami paper, LEDs, tape, scissors, coin battery (We purchased batteries, and LEDs from Adafruit)

We found origami videos on Youtube and set out iPads.  We found that it’s easier for teens to follow origami on video than in a instructional booklet. We did a heart origami and showed teens how to insert the LED in the fold of the heart with tape.

Intermediate-LED Hoodie & Backpack ($60 for 20 teens)

Materials: Hoodie, thread, needle, EL Wire

Have teens bring in a hoodie.  Have teens begin sewing the EL wire on one side of the zipper.  They should sew the wire in small increments all the way around the hoodie to the other side of the zipper.  They should then cut a small hole on the inside of the pocket on the side with the slack.  String the slack through the pocket, connect the battery pack and that’s it.

You can use hot glue on the EL wire.  The backpack was made but hot gluing the wire.  This also looks cool on baseball caps.

Intermediate-LED Wristbands ($75 for 20 teens)

Materials: Felt or fabric, conductive thread, LED, snaps, coin battery (We purchased everything except the fabric from Adafruit)

Please see the diagram from instructables.

When teens snap the wristband shut, the LED should come on.
