Read/store data from an LED voltmeter (300v) to a computer using arduino

hello guys! im a complete stranger to arduino but would definitely want to learn about it.

i have a project wherein i need to store the data of an led voltmeter (the ones bought from ebay and amazon) to a computer automatically. can an arduino help me with this? the voltage range would be at about 170v to 240v dc.

More details, please.

More details, please.

Unless the LED voltmeter has a RS232 interface there is no point in doing this.

And if the voltmeter does, why use an Arduino ? It makes no sense!


These are high voltages, unless you know what you are doing - avoid .
240DC can easily kill

Many good multimeters have an opto-isolated USB serial interface which is exactly what is needed hereā€¦
