What you'll build
A project that doesn't quite work — find the bugs and fix them like a real technician.
Before you start
You'll learn: Debugging method: read the error, fix one fault at a time, re-test after every fix.
You'll finish: A broken button-and-LED project that you diagnose and repair yourself.
Real world: This exact routine — observe, isolate, fix, re-test — is what every repair technician does all day.
Then try: Swap broken projects with a friend and race to fix each other's, or log each fault you find in a repair notebook.
Who does this: Phone, appliance or electronics repair technician — TVET, or a repair business of your own.
