PIC diode tester Circuit
This is a simple use of the PIC 16F84 about a diode tester.
Test procedure : We set �1� to PB0 and �0� to PB3. If diode is ok and opens, then at PA0 we have �1�. If PA0 is �0�, then the the diode has problem. With the program we manage what the PIC will do in each situation . If PA0 is �1�, green led lights wich means that the diode is OK and if PA0 is �0� red led is lighting and the diode is problematic
Test continuous as follows: We give �0� at PB0 and �1� to PB3. If diode is OK and opens, then at PA0 is �1�. If PA0 is �0�, then diode has problem. If PA0 is �1�, green led lights that means that diode is OK and if PA0 is �0� the red diode is lights that means the the diode is problematic.
