Hello everybody. I am new with these Arduino boards and just playing around with how to program them. I am looking for some help on a design and program.
I am looking to take a 0-10VDC signal as my input signal and convert that into a 0-5VDC output signal that is inversely related to the input. So if I have 10VDC in I need 0VDC out and 0VDC input would give me a 5VDC output. As the input rises the output falls within these ranges.
I have looked into various circuit designs but can't seem to come up with anything on this so far. I was wondering if using a small board would work with a little programming to tell it how to relate the voltages.
Any help or ideas would be great.
