This simple micro ampere meter circuit can help in measuring small currents in five ranges: from 1 µA to 10 mA. The meter is working in this way: the current being measured Ix shifts the input voltage ...

The circuits were designed using two A/D converters to create a voltmeter and ampermeter. The circuits are designed with the combination of CA3161E and CA3162E to imposing a complete 3-digit display ...

[Aleksejs Mirnijs] needed a tool to accurately measure the power consumption of his Raspberry Pi and Arduino projects, which is an important parameter for dimensioning adequate power supplies and ...
