Intro: LED Throwies
Hello everyone. This is yet another instructable on the LED Throwie.
Step 1: Materials
- 5mm LED's of different colors
- 3v coin cell battery (Mine is CR2032)
- Scotch tape
Step 2: Test the LED
Take the LED and put the long prong on the flat side of the battery. Take the short prong and put it on the long prong. The LED should light. If you are a beginner and you have read my previous instructable on how to use LED's, you may be wondering why there is no resistor. The answer lies in the battery. The battery is small enough that its body provides enough internal resistance to keep the LED's from exploding.
Step 3: Taping the LED to the Battery
Take some scotch tape and peel off a strip about 3 inches long. wrap in around the prongs of the LED and the battery. Give it a toss into the air. The pieces shouldn't separate.
Step 4: Make Some More!
As with many LED toys, these throwies are more fun in a group. Make several more of different colors and hand them out to your friends in a party at night. These toys will provide hours of fun in the dark.
