Hi,
64GTO:
If the power to the controller is 12-14 volts from a lead acid battery can I run jumpers from there to Vin on the Arduino?
If you are using a lead acid battery please fit a fuse in the positive wire at the battery.
Lead Acid batteries can supply huge amounts of current if confronted by a short circuit, this can be very destructive to electronic components and wiring.
Thanks.. Tom..
