I want to use my PC to control a home made AC generator project. In particular I want to be able to monitor the AC voltage of the generator, which should be 50Hz, 240V AC, but will fluctuate a little.
Can I use an 8055 to do this ?
I can’t find anything online about the analog input range, but I presume it is 0-5Vdc.
My current plan is to use a transformer to step the voltage down, and then rectify the AC to DC. The smallest transformer I have found will give me 6V ac, which once rectifed will be a little over 8V dc. So I plan to apply this across two 1K resistors and connect the analog input across one of the resistors.
Will this give me an accurate measurement of the ac voltage, or can you recommend an alternative ?
