Resettable Amp Hours Transaction Meter?

[MEXICOWANDERER]

• Don't need or want voltage display
• Don't need or want Peukert conversion
• Nor selectable menu options
• Want LCD or LED meter that displays ampere hours transactions
• Reset to zero with a push of a button

My abysmal internet connection thwarts comprehensive searching.

But maybe a meter like this does not exist

I'd hate to waste 500 hours confirming it.

Thank You In Advance

Good Day!
This should do the trick,

Divide by 12 if you want amp/h.
May I ask why you want amp/h instead of w/h ?

Current transducer, hall effect, works on AC or DC

Jeeze eBay links are a mess

There's tons of getting started guides online for Arduino. Mostly learn by example stuff. Lots of examples based on the ACS712 transducer, smaller brother to what's linked above.

Grab a few Chinese Arduino clones with USB on board, makes programming a lot easier.

Arduino Pro Micro for example

CT for DC?

AC uses kWh

Need for DC

Is there are good primer for Arduino? I don't need to nor have time to reinvent the wheel.
