I had this idea to diy a web cam staring at three digital multimeters, taking that info, reading the numbers, and making a real-time running graph. Should be possible yes?
I’m going to start this search by
1 posting idea here to see if any of the community has already done it, or knows where to look
2 starting with Arduino hardware and projects
And finally
3 updating this post with my findings and project.
Any input would be great, thanks!
How to OCR digits real time and use that value in Arduino?
Don’t need arduino, can do OCR from an video stream on the computer using a webcam.

@pinholer neat idea too! Here's a howto I googled. eBay links are dead, but the parts and schematic are probably good. Arduino based multimeter for current voltage indcutance capacitance and resistance

Use Arduino analog to digital converters and read voltages directly with voltage dividers to scale the inputs to 0 - 3.3V or 0 - 5V depending on the specific board. You can display the results to a graphics screen or save to memory card for analysis later. Simpler than video and OCR.
