The hardware

The CircuitKid Kit

Every part for the whole course and all 5 capstone projects, shipped to your door in one box. Sorted into labeled cases before it goes out, so day one is not a mystery bag of parts.

Lesson 1, finished

A look inside the box

Real photos of the actual kit on my desk. Not stock images, not renders. What shows up is what you see here.

  • Close-up of the LCD1602 display showing 'I heart Arduino'

    It really says hi

  • Sorted cases of sensor modules and a membrane keypad included in the kit

    Everything, organized

  • Relay, joystick, ultrasonic sensor, water sensor and power supply modules

    Joysticks & gadgets

  • Case of sensor modules including sound, light, temperature and tracking sensors

    30+ sensor modules

  • 2WD robot car chassis with four wheels, motors and hardware

  • 4 × AA batteries for the motor and robot car projects.

That's genuinely it.
