What's in the Intro to Circuits Kit?

The Intro to Circuits Kit is the starting point. It holds the rechargeable battery, the core circuit blocks and printed instructions for six builds, all in a carry case with a foam insert.

The electronics

  • 1x USB-C Rechargeable Battery Block (4x8 stud)
  • 1x High-Speed Motor Block (R300)
  • 4x LED Blocks: Red + Blue (1x4), Warm White (1x4), Green (1x4), Rainbow (1x4)
  • 1x Speaker Block
  • 1x Siren Sound IC Block
  • 1x Slide Switch Block
  • 1x Push Button Block
  • 1x Potentiometer, the dial control
  • 1x Photoresistor, the light sensor
  • 8x Wire Blocks: 2x 1x4 red, 2x 1x4 black, 1x 1x3 red, 1x 1x3 black, 1x 1x2 red, 1x 1x2 black

Everything else in the case

  • 1x USB-C charging cable (20 cm)
  • 20+ assorted building bricks
  • 30 page printed assembly instructions
  • 24 page printed Learning Guide
  • Reusable plastic carry case with a foam insert and a labelled parts overlay
  • Sticker set

The six builds

The printed instructions are word-free, so a child who is not reading yet can still follow them.

  1. Helicopter
  2. Personal Fan
  3. Merry-Go-Round
  4. Covert Morse Code Machine
  5. F1 Car
  6. Random Number Picker, with a printable number page

Every PDF, plus the build-along videos, is on the Intro to Circuits Kit resources page. Learning Guides in French, Spanish, German and Dutch are on the Languages page.

One thing worth knowing before you open it

The kit ships 20 or so loose bricks, which is enough for the six official builds. It is not enough to invent much beyond them. Almost every family uses their own brick collection from there, and that is how the kit is meant to work. If you have no bricks at all in the house, expect to want some.

What it does not include

No transistors, capacitors, resistors, gearbox motors or remote control. Those are in the Expansion Kit.
