desmond Posted April 5, 2004 Report Share Posted April 5, 2004 I am a beginner in electronics design, currently i am stuck in a simple project, hopefully i can get some advise from you how to solve it.I am current doing a simple project on short circuit checker. I have to check on some pins of a chip on a PCB. I need to touch on the pins at once and check out exactly which pins are shorted, for example there are 10 pins, i need to know whether pin1 and pin2, pin2 and pin3, pin3 and pin4 and so on are shorted or not ..I am only allow to use 5VDC power supply. At first i was planning to use LEDs to design a always "ON" LEDs simple circuit, when the pins are shorted, the LED will go off, but i failed to do so.there are internal connection among the pins, some have 200k.ohms, and some have even M.ohmsHopefully i can get your reply ..Thanks in advance Regards,Desmond Quote Link to comment Share on other sites More sharing options...
