I'm a total newbie to Arduino and I'm starting my first Arduino project and I figured, meh, why make it easy?
I'm building a electric mini chopper that will be powered be a 48v 12ah battery pack. My controller can draw up to 200 amps max and I want to make a "fuel gauge" that shows both volts and amps.
Just to clarify, a fully charged 48v pack is actually around 57 -58 volts, so I want the voltmeter to read up to 60v. I would like the ammeter to read up to 200a if possible. I do understand that I will need a good quality shunt for something like this.
I've found a couple of post on different website on how to make individual voltmeters and ammeters, but I haven't found any that combine the two.
I'm planning to follow this tutorial to make the speedometer/tachometer:
So I would like to use the same display if possible.
I have "OK" coding skills in a couple of different languages, (I put the OK in parenthesis because my son is a developer for Openstack SDN and he laughs at my code! ), so I'm not afraid to approach this project as a beginner.
Does anyone have any suggestions?
