LED Bracelet Instructions
Materials ! You will need:
! 1 strip of felt ! 1 LED
! Condutive thread ! Regular thread
! 1 CR2032 battery
! 1 battery holder ! 1 LED
! Decorations ! Sewing needle and scissors
LED’s ! Light Emitting Diodes
! Emit light when electricity runs through them
! Only work if the electricity is going in the right direction
! If you connect the long wire to the positive side of the battery and the short wire to the negative side, it works
! Connect it the wrong way, though, and nothing happens
Step 1: trim the felt to fit your wrist
Step 2 – add snaps ! Using conductive thread,
sew one half of the snap near the end of the strip (sew lots of conductive thread through the loops of the snap to make a good connection when the snap closes)
! On the back side of the strip sew the other half of the snap so that when the strip is closed in a circle, the two halves snap together
Step 3 – add light ! Cut a slit in the strip for the
LED lighs
! Poke the LED light bulb through the hole so the metal is on the back and the bulb is on the front of the bracelet
Sew lights & battery holder
! On the back of the bracelet, sew the positive (square) side of the LED to one of the snaps
! Sew the positive side of the battery holder (the one with the three plastic prongs) to the other snap
! Sew the negative (round) side of the LED to the negative side of the battery holder
! Slip the battery into the battery holder negative (rough) side down
Decorate ! Add decorations to the
front of the bracelet – fabric glue or felt glue is great for this
! Snap the bracelet on your wrist and watch it light up
