Hi guys, im building a 7 channel volt meter. Can i do this with a uno or do i need to go to the mega? Or can i add a shield? any help will be greatly appreciated.
You can use external ACD's, build in ADC is not super high resolution or something. Or use Muxes to switch the channels.
The Pro Mini has 8 analog inputs.
thanks guys for your info
Hi,
What voltages do you want to measure and what resolution do you need?
Are they with reference to a single point, or different references?
