Signal tracer
Follow the signal until good becomes bad.
Practise stage-by-stage probing for power rails, audio paths, radio tuning, and sensor logic on safe low-voltage examples.
Safety first, always.
ElectroLab AI teaches theory, low-voltage electronics, and planning concepts. Mains voltage, switchboards, fixed wiring, high-current systems, and legal electrical work must only be performed by licensed electricians where required.

Use Scope Lab to practise what good, clipped, noisy, rippled, and square signals look like before tracing a fault.

DC power path
A low-voltage project is dead even though the battery should be charged.
Probe points
Start at source
Confirm the signal exists before blaming the load.
Move downstream
Probe stage by stage until good becomes bad.
Change one thing
Repair one likely cause, then measure the same path again.
