PIC voltmeter can measure 0-70 Volts which should be more than enough for most of electronic projects providing excellent reading accuracy and resolution. It has two input channels for measuring two voltage sources at the same time. This PIC voltmeter project uses PIC16F876 microcontroller with built-in ADC (Analog to Digital Converter) and 2x16 backlighted LCD display.
Build Accurate LC Meter and start making your own coils and inductors. This LC Meter allows to measure incredibly small inductances making it perfect tool for making all types of RF coils. LC Meter can measure inductances starting from 10nH - 1000nH, 1uH - 1000uH, 1mH - 100mH and capacitances from 0.1pF up to 900nF. The circuit includes an auto ranging and reset function to make sure the readings are as accurate as possible ... [more]
