Any suggestions how to easily differentiate between 1.0 VAC and 1.5 VAC. The current will be low (~340 mA). I do not need to read the actual value, just tell the difference between the two readings. Can I bring that AC voltage directly into the Ardunio? If so, can I just collect data and then look for the MAX value? Any other suggestions? Does anyone have any sample coding?
I need to differentiate (48) signals, so plan to use the Mux Shield. Anyone have any sample code for this?
Thank you & Hope you have a nice day!
