Master physical computing with proven techniques, safety tips, and collaborative coding strategies.
Physical computing follows: Input → Process → Output!
Data from sensors & buttons
The Micro:bit brain runs your code
Results via LEDs, speakers, motors
Input: Light sensor detects darkness +
accelerometer detects movement.
Process: Code checks: "Is it dark AND
is there motion?"
Output: If yes → LEDs on. If no → LEDs
off.
Two heads are better than one! Code together effectively.
One person is the "Driver" and the other is the "Navigator". Switch roles every 10–15 minutes!
Great makers test early, test often, and never give up!
Sketch your idea on paper first. What inputs and outputs will you use? A clear plan saves time!
Start simple — get one LED blinking first. Then add features one at a time.
After every change, test your code! Use the MakeCode simulator first, then the real board.
Check connections, review code block-by-block, use "show number" to display values, and ask your Navigator!
Reinforce cardboard, tidy wires, add decorations. Make it look amazing for your presentation!
Keep your Micro:bit safe with these important guidelines!
Never apply hot glue directly to the circuit board. Use tape or mount in a case instead.
Use an expansion board (like the Boson board) for multiple modules — prevent messy wiring and short circuits.
Use correct 3V battery pack. Don't mix old and new batteries. Remove when not in use.
Micro:bit is not waterproof! Keep away from liquids and wet surfaces.
Be careful with USB and battery connectors. Pull straight — don't bend or wiggle.
Sort components in labeled containers, manage cables, and keep tools organized.
