The logic behind circuits is no longer top secret! With this kit you can create four kinds of intruder alarms with voice warnings, secret message sending and receiving devices, a pressure-activated security mat, a metal detector, or a lie detector. Each device is assembled using combinations of logiblocs - interactive electronic building blocks that plug together to create circuit systems that make things happen. Comes with 10 logiblocs, one jack plug, two pressure mat cards, stickers and instructions. Ages 7+ |
