Lefty, the extent of my voltage readings related to the accuracy of the voltage on the LCD versus the actual voltage of the battery. They were very similar. I did not measure current, as it was not even a consideration in my mind (again, my lack of knowledge). I wouldn't know what is suspect or what is the norm.... nor would I really randomly think of where I should be metering with regard to current. Do you have any suggestions?? My background is in user interface design (high level), so aside from the half-dozen explorations I've done with the Arduino platform, I really haven't gone too far, and I certainly don't have an electronics background. I'm trying to learn though, project by project. I find it fascinating and I am enjoying the process, but trying to piece together decades old C programming knowledge, and basic electronics is tough..... the whole old-dog-new-trick thing. :-)
Test 1. Measure the voltage right at the analog input pin you are using and one of the arduino ground pins, write down value and polarity.
Test 2. Wire your current meter in series between the analog input pin you are using and the wire coming from the battery. Have the red meter lead at the analog pin side. Then write down the value and polarity of the reading.
You must of course set up the meter leads and functions properly for measuring voltage and current as they are different and the details depend on your specific meter.
Get back to us with the findings and we will take it from there.
