Emerging Technology & 3D Printing at Centennial Libraries

Learn about the library's technology collection and 3D printing service! Borrow resources like Arduino, Raspberry Pi, virtual reality headsets, podcasting kits & more!

What is it?

Little Bits Kits allow you to create simple circuits with magnetic parts. Learn about power, switches, and motors and easily incorporate electrical components into prototypes and designs.

Borrow It!

Click on a piece of technology to see if it's available in the library and place a hold to reserve it. Watch this video to learn how to place a hold. If the item is available, you can also come to your campus library and ask for an item to borrow it. 

Getting Started

LittleBits includes different types of colour-coded magnetic modules. Place the modules in different combinations to create different kinds of circuits. Each circuit should have a:

Blue Power Module This will start every circuit you create
Pink Input Module This will send signals to the modules after it
Green Output Module This will complete an action or task

Follow these steps to create your first circuit:

1. Connect the battery & cable to the blue power module & turn it on
2. Connect the blue power module to any pink input module
3. Connect the pink input module to any green output module
4. Press the button, switch or lever on your pink input module & then see what happens!

TIP: The magnets in each module will only connect one way. If you're having trouble connecting your modules, try rotating them until they fit together.

You will need: 

  • LitteBits modules (power, button, wire, bright LED)
  • cardboard tube (e.g. toilet paper or paper towel roll), 
  • rubber band
  • plastic cup

1. Start by building a simple circuit:

  • Connect the battery & cable to the blue power module
  • Connect the blue power module to a pink button module
  • Connect the pink button module to an orange wire module
  • Connect the orange wire module to a green bright LED module

2. Place your circuit on top of the cardboard tube & wrap it with an elastic band. Fit the battery & LED inside the tube.

3. Place a small cup in the front of the tube to diffuse the light.

4. Turn on your power source & press the button to go exploring. 

For Educators

Interested in using LittleBits in your classroom, but not sure where to start? Contact your librarian, Natalie Colaiacovo ( for support and resources. 

Use LittleBits to introduce your students to:

  • Engineering & electronics
  • Product design & innovation
  • Entrepreneurship

Students can:

  • Prototype new projects & inventions
  • Engage in project-based learning
  • Find solutions to modify existing products
  • Learn problem-solving & creative thinking skills

How is LittleBits Used in the Classroom?

Not sure how LittleBits applies to your classroom? LittleBits could be used in ANY classroom -- not just STEM classrooms.
Beyond helping users understand basic electricity & circuitry, LittleBits can be used to teach innovative thinking, problem-solving, design & teamwork. Here's how:

  • Before a group assignment for your course, have your students work together on a LittleBits project to encourage communication & teamwork among group members
  • If students need to design a product for a business or design course, have them use LittleBits to prototype their design
  • Want your students to think outside the box? Have them practice by using LittleBits to create something new
