Forgive me, but I'm new, so this question might seem dumb, but what can you do...
I am working on a project that uses two large servos to move a Christmas decoration when someone approaches it. It's hard to explain. But I want to make it a permanent thing, so I was thinking of using a Arduino Pro Mini328 to run it. The two servos are quite powerful, and use up to 400ma of current at 6 volts each. I'm using a 2 amp, 12VDC tranformer that I have that used to power an old external disk drive to supply power to the device.
What I was thinking was to build a voltage redulator circuit with two 7806CT regulators, caps, and diods to supply 6VDC of regulated power (I could use just one, but they are only $0.50, and redundancy seems prudent) to the project. Can I run the servos and the Arduino off this circuit? Would I get any issues from hooking up two large servos and the microcontroller together?
The arduino schematic
says that the arduino pro has a maximum voltage input of 16VDC. Should I just run a wire straight off the 12V transformer to power the arduino separately?
