Computer Aided Design (or CAD) is where we use computers to help (or aid) us with design.
Light Box
Design a light up sign in a box. Use software to help.
Microbit
We will put a BBC Micro:bit inside the box to light it up. This will give us control using code.
Wiring the micro:bit
To control the light box from outside, we need to connect wires to the micro:bit.
Your Light Box
The finished box will light up when we control the LEDs on the micro:bit.
