A weblog focused on interesting circuits, ideas, schematics and other information about microelectronics and microcontrollers.
PIC Autorange Capacitance Meter
Really powerful autoranged capacitance meter based on PIC16F873. It means users does not need to adjust the range settings. The measuring range is quite large, from 5pF to 2600uF.
Device operation is based on a very simple circuit analysis principle of charging and discharging of capacitors in an RC circuit.
