Currently I have it only to usb and not wired up to anything, i believe that the usb supplies 5v but could be wrong. I do also have a power shield and the device reacts the same when hooked up to that.

I dont have a full circuit diagram at the ready but i can tell you that i have 7 of the circuit found in the link below as well as some simple circuits for sensors, dsb1820, a few float valves, etc.

Here is the like referenced above

> My mistake, i had ordered 12 & 5 volt voltage regulators and must have used the wrong model number, thanks for pointing that out. Is this something that would work for what i’m doing? Ive removed the LVT and fixed the connections. . Assuming its all good now, how would I say add three more of these? Do i run all of the components in parallel?

I have tried almost everything i could find on the forum to no avail.

Thanks
