| Oct 8, 2014 at 19:14 | comment | added | David Kerr | It's highly simplified due to a lack of components on Every Circuit. I would probably attach a voltage regulator in there. The OpAmp gets powered by the battery, the mains or the capacitor depending on the situation (ie its power is from the negative and positive rails on the diagram). I'm new to electronics, but I based this circuit off examples and advise from around the internet. | |

Next, you appear to back-drive the mains supply when it is unpowered - that may or may not work, for example, it may load the battery supply. Finally, you appear to be supplying either 5v or 9v, but the typical arduino does not have any power input which can accept both of those values and function as intended. | |
