Capacitors are vital components in electronics, but sometimes they are broken, or the value printed on the cap has become unreadable. Because my multi-meter does not have a capacitance measurement, I decided to make one!The principle of measuring capacitance is quite simple. The voltage of a capacitor charging through a resistor increases with time T. …
This is a simple application of internal 10-bit ADC(analog to digital  converter) of PIC16F676 microcontroller.you can use this  circuit  to measure  up to 30 v dc. the possible  applications are on bench top power supply or as a panel meter in various system. Circuit description       MICROCHIP’S PIC16F676 is the heart and brain …
