Crack the Code · Interactive learning path

See it in 3D.
Build it step by step.

Bring your kit to life with 20 guided projects. Start with your first blinking LED, then explore sensors, sound and a working pedestrian crossing.

Explore the parts. Follow the steps. Make something happen.

The actual 3D potentiometer cutaway, revealing the moving wiper, resistive track and current flow. Explore this model in 3D
Turn it. Open it. See how it works.

Electronics you can explore

Rotate the models, reveal their insides and watch components respond. Follow current through a knob, press a button or shine light on a sensor.

A clear next step, every time

Work through wiring, explained code and checks in order. Start with a working example, change something, then test your idea on the real kit.

Code in English. Upload in Chrome.

Use the English IDE to turn plain-English instructions into Arduino C++. Inspect the code, then Verify and Upload to your Uno from desktop Chrome.

Explore the potentiometer

This is the Components Kit for CTC (Crack the Code). The Crack the Code unit of work addresses 25 hours of the Digital Technologies context in the new Technology Mandatory syllabus in NSW.

Designed for educational purposes in mind both at home and in school, we've put together the very same parts used in the CTC kit! It includes a 10K Potentiometer, 5mm LEDs, a Buzzer, a light-dependent resistor (LDR) and a pushbutton.  

Even if you're not in school, these kits make a great starter set for your Arduino, Micro:bit or Raspberry Pi projects! With these versatile parts, you could learn how to turn on a light, understand sensors or gain hands-on experience with making other simple circuits.

Jargon buster

Plain-language definitions for the technical terms used above.

photocell
A light-sensitive component whose electrical resistance changes with the amount of light falling on it. It matters when choosing or using light sensors, automatic lights, or brightness-detecting circuits because its response speed, resistance range, and sensitivity affect how reliably it detects light levels.
potentiometer
A variable resistor usually turned with a knob or shaft to create an adjustable electrical signal. It is often used for inputs such as volume, brightness or position, so it helps beginners learn how a microcontroller reads changing values.
