AC Voltmeters and Ammeters - AC Metering Circuits

Arduino, come ben sappiamo, grazie agli ingressi analogici pu essere usato per misurare tensioni da 0 a 5V. Per valori superiori useremo un partitore di tensione formato da 2 resistenze in serie, e misureremo la tensione del nodo centrale collegandola all`ingresso analogico A0.

Microcontroller Voltmeter Ammeter with LCD

ooked it up to an arduino, found a routine on al gores interweb and used that chunk of code to give me a more accurate reading. compared it to DC clip on ammeter and it works fine for our purpose - sensing when the motor reaches 6 amps.

Digital DC watt meter using pic microcontroller

Voltmeter Ammeter uses very few external components making it possible to fit this handy meter on a small PCB. The meter provides exeptionally accurate readings due to buit-in software based calibration and the use of 1% metal film resistors. Using single supply to measure voltage and power Volt Ammeter kit. Arduino Prototype is a
