A kit of parts to build a test probe that will indicate the logic levels in your circuits.
Circuits are often tested with multi-meters and oscilloscopes, but this is not always the best method. For example, not everyone has access to an oscilloscope and multi-meters are no good for fast-changing signals. Another reason is ease of use: testing a circuit with an oscilloscope can be tricky as you need to probe the contact and then turn away to look at the display. All it takes is for the probe to slip slightly and then the oscilloscope will be showing the signal trace for a completely different connection.
This is where the logic probe saves the day! Instead of having numbers to show voltages, or a display to show signals over time, the logic probe has just three LEDs for outputs. These outputs can show On, Off, Floating, and Oscillating! So long as the probe has a common ground to the circuit under test (which can be done easily by either using the same power supply or connecting the probe's GND-REF to the circuit's ground), the probe will display one of the four listed conditions above when connected to a point in the circuit. But how does this probe work? Get this kit and find out!
