An "improved" inductance / capacitance meter Actually, it works much the same as the originalIt differs from the original in that: A 16F628 PIC is used. This has internal comparator, which means the LM311 is no longer needed.Software calibration is used. The finished meter can be calibrated against "any" accurate capacitor within the range 100pF to about 10000pF -An "improved" inductance/capacitance meter Actually, it works much the same as the originalIt differs from the original in that: A 16F628 PIC is used.
