[Paulo]’s got a few solar panels on his shed, and while he does have a fairly nice setup with a battery charge controller, he found himself looking around for a panel voltmeter. Of course you can buy ...

Here is a Simple LED Volt meter to Monitor the charge level in Lead Acid Battery or Tubular battery. The terminal voltage of the battery is indicated through a four level LED indicators. The nominal ...

A voltmeter and ammeter are to an electrical system what a pressure gauge and a flow gauge are to an oil pressure system: A voltmeter measures electrical pressure in volts; an ammeter measures ...

Our last article covered voltage troubleshooting in series with power-consuming devices (motors) [“Electrical Troubleshooting,” March 5, p. 16]. The article differentiated between an open and a closed ...

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 ...

The Volt meter clock continues our recent slew of interesting clock projects. Though considerably easier to read than the resistor clock, it is in the same frame of mind. Set up to look like the face ...
