Hi Guys, I am trying to make a cable tester (each cable has 4 wires). Basically, I am looking for continuity
test, also if there is any short circuit/open circuit. An LED to indicate the status of each wire would be
great. Based on that I can pass or fail the cable. I have tried
couple of techniques already discussed on the forum but unfortunately they have cost me 2 Arduino UNO
boards. I think with my basic knowledge, I haven't been able to implement them correctly. Can anyone
please guide me through the process with circuit diagram and a piece of code. Thanks in advance.
