it will only supply about 100mA
Hi, I have meant to do an update on this but also haven't had the time. Except for using stepper motors instead of servos I haven't really thought about many improvements so far
Great Job! excellent Instructable

I'm not too sure what you mean, this will only monitor the 5v supplying the Arduino. If you are supplying power from a wall supply then why do you need to monitor the voltage? If you want to monitor the voltage from the batteries then you just need to analog read the voltage of the batteries
No it won't, it needs at least 4v
