Crack the Code

Crack the Code is the NSW Technology Mandatory 7–8 design project, rebuilt as a self-paced course on Little Bird. You'll go from your first `digitalWrite(LED, HIGH)` to a complete alarm/alert system using a real Arduino + ThinkerShield kit. By the end you'll be reading buttons, potentiometers and light sensors, driving LEDs and piezos, and writing real Arduino C++ — the same code your kit ships with.
