Circuit Detective

Step into your electronics workshop and learn to solve faults, one measurement at a time.

Circuit Detective combines a diagnostic game with a virtual 3D laboratory. Inspect components, follow circuit traces, place your probes and test your ideas against measurements.

77 MISSIONS TO BUILD YOUR SKILLS
Start with resistors, LEDs and switches. Then explore capacitors, diodes, transistors, rectification and signals. Measure, calculate, choose a component or identify a fault.

INVESTIGATIONS AND GUIDED PROJECTS
Finish the progression with four investigations: measure, find the fault and check your repair. Three guided breadboard projects take you step by step through building a circuit. After each successful mission, explore the schematic and the explanation of your result.

HANDS-ON VIRTUAL INSTRUMENTS
Use a multimeter, a two-channel oscilloscope, a function generator and an adjustable power supply. Rotate around circuit boards, zoom in on components and inspect the solder side.

A WORKSHOP FOR EXPERIMENTS
Practice diagnostics and repairs, replace components and build circuits on a virtual breadboard.

UNDERSTAND AS YOU PLAY
Read lessons, component datasheets and hints. Use the built-in calculator to work through your measurements. Your progress is saved on your device.
