Logic Probe Kit (KIT10S)

In modern digital electronics it is necessary to be able to detect high speed clock pulses in addition to DC logic levels of inputs and outputs. This circuit will allow you to do all of the above. You can follow logic (1) and (0) through a circuit under test.

Logic (1) is indicated by a red LED and (0) by a green LED. A yellow LED indicates pulses and a switch switches polarity.

Items NOT included in the kit, but available separately, are:
5V DC Power Supply.
Probe.
