Use ATmega8, ATmega168 or ATmega328 microcontrollers.
2x16 character LCD display shows the result.
One-key operation, automatically turn off the power.
The shutdown current is only 20nA, which supports battery operation.
The low-cost version does not require a crystal oscillator and supports automatic power-off. ATmega168 or ATmega328 with 1.05k version software uses sleep mode to reduce power consumption when there is no measurement.

Automatic detection of PNP and NPN bipolar transistors, N and P channel MOSFETs, JFETs, diodes, double diodes, thyristor thyristors.
Measure the current amplification factor of the bipolar transistor and the threshold voltage of the emitter junction.
Darlington transistors can be identified by high threshold voltage and high current amplification factor.
Detection of protection diodes for bipolar transistors and MOSFETs.
Measure the threshold voltage and gate capacitance of the MOSFET.
20. Measure the reverse capacitance of a single diode. Bipolar transistors can also be measured if you connect the base and collector or emitter.
Only one measurement is required to find out the connection of the full bridge.
Capacitors below 25pf are usually not detected, but can be connected in parallel with a diode or at least a 25pf capacitor in parallel. In this case, you must subtract the part of the parallel capacitance value.
Resistance below 2100 ohms will measure inductance, if your ATMEGA has at least 16K flash memory. The range will exceed 20H from 0:01mH, but the accuracy is not good. The measurement results only show a single component connection.
The test time is about two seconds, and only capacitance and inductance measurements will take a long time.
