70V PIC Voltmeter Amperemeter (Parts)

PIC Voltmeter Amperemeter can measure voltage 0-70V with 100mV resolution and current consumption 0-10A with 10mA resolution. It is a perfect addition to any power supply, battery chargers and other electronic projects where voltage and current must be monitored. The meter uses PIC16F876A microcontroller with built-in ADC (Analog to Digital Converter) and 16 x 1 green backlighted LCD display. Circuit design uses very few components and may be mounted on a small PCB.

Dual Channel 70V PIC Voltmeter (Parts)

PIC voltmeter can measure 0-70V voltage providing excellent reading accuracy and resolution. It has two input channels for measuring two voltage sources at the same time. PIC voltmeter project uses PIC16F876A microcontroller with built-in ADC (Analog to Digital Converter) and 1    6x 1 backlighted LCD display. Circuit design uses very few components and may be mounted on a small PCB.

This item comes with the parts required to build Dual Channel 70V PIC Voltmeter except for PCB. Voltmeter can also measure AC voltage if rectifier diode is added to voltage input. This meter can both measure and be supplied by the same power source.
