[Amps] DIGITAL BARGRAPH DISPLAYS

Has anyone seen an alternative if one would like to build an ammeter with such a bargraph? It seem the ones on Ebay are configured as voltmeters. Don’t know if they easily can be converted to ammeters by removing some resistor…

Steve,

Whatever you need, this company has one...

If you want to go old school, the common chip to base it on is LM3914.
