Hi, I am now doing my final year project.I am going to do a Bipolar Junction Transistor Tester by using PIC. It can test out the type of the transistor either NPN or PNP. Bedise that, it can identify the pin of the BJT transistor(Collector, Emitter, and Base) and the current gain(Hfe).Those results is display in LCD. Anyone can introduce any suitable website or material about how to make a BJT transistor tester using PIC for me?? What I found from this forum center is quite good, anyone can check for me?? Thanks for your help!!!

To check the gain, the tester needs to be able to measure the ratio of collector to emitter currents. This will need a PIC with ADC built in.
The other Transistor tester discussed in this forum does not have this, besides, it tests for FETs too.
My advise would be to study that schematic for ideas and then modify it for measuring the collector (or emitter) current while forcing a known current into the base.

What you mean is to produce out collector current
to produce the base current, is it right?
Do you have any website or examples about this?
What I found here is from ELEKTOR, it can just test BJT transistor as what I want but I need the source code of the PIC.You have any idea about it.
