littleBits Code Kit

littleBits are electronic building blocks – called Bits – that snap together with magnets to create circuits. Each Bit is color-coded by its function (power, input, output, and logic) in the circuit, providing a simple and intuitive user experience. In addition, all Bits are compatible with each other, allowing countless creative possibilites.

This code-based learning kit contains three littleBits Code Kits for a total of 60 Bits, 78 accessories, free desktop app, and online tutorials, handouts, and tips and tricks pages. Whether working alone or in small groups of 2-3, kids will be engaged in computational thinking through building circuits and programming. They will get a hands-on understanding of "what's inside the machine" and how it connects to the software.
