Locate a really cool
electronics kit that measures something. What does it do? .5 points
- Electronic Dice Kit
- The Dice Kit is a beginner’s soldering kit that comes with everything you need to make your own electronic die. When you tap it on the table, it displays a number from 1 to 6 by lighting up the appropriate number of LEDs in the same layout as found on traditional non-electric dice.

There’s no programming required and a beginner can get the kit together in about an hour or so. You will need a soldering iron and basic tools. Also, a dab of glue or double-sided tape is recommended as well.
