Create Working Electronic Circuits Snap Circuits comes with over 30 pieces to create 101 different electronic projects. The pieces, which include snap wires, slide switches, an alarm circuit, a music integrated circuit, and a speaker, snap together easily on the included plastic grid--no soldering required. Each piece is numbered and color-coded to make identifying them easy. These components combine to create working circuit boards just like the ones found inside televisions, radios, and other electronic devices. Simple, Fun Projects Let Kids Learn While They Play With its easy-to-follow instructions, Snap Circuits gives your child a hands-on education in how electrical circuits work to run the everyday devices that they're familiar with. They'll also gain valuable lessons in building and in following instructions. The project manual includes large color illustrations and simple directions for each project. The projects include a sound-activated switch, a musical doorbell, a voice-controlled lamp, a flying saucer, and a light police siren. With these projects, children will experiment with things like electric switches, integrated circuits, digital circuits, fuses, and the transformation of circuit sounds into other sounds. Grow as You Go Because the projects are arranged in order of complexity, kids can build on their skills as they progress through the manual. The lessons start out with a simple electric light and switch project that demonstrates how electricity is turned on and off with a switch. Further along, kids can put together a two-speed fan, create clap-controlled sounds, and more. Design Your Own Circuits and Upgrade Your Kit Once children have mastered several of the techniques introduced in this kit, they can use the components to experiment and create their own customized circuits and electronic devices. The Snap Circuits Jr. SC-100 can also be upgraded to the Snap Circuits SC-300, Snap Circuits Pro, or Snap Circuits Extreme with the purchase of a UC-30, UC-40, UC-60 upgrade kits, respectively. Kids will enjoy additional parts, manuals, and projects that'll take their kit--and their fun--to the next level.
