I want to power my motor driver and arduino board using the same 12V lead acid battery. The current draw for the motors will be 6.8A and 18.6A for normal and heavy usage separately.
For a single power supply like this, do you know what components or circuits should I use to protect the arduino from the interference of the motor? Do I need to put a resistor in series with arduino to limit current or something else to prevent arduino from resetting when the motors draw a lot of currents.
I am pretty new to electronics and arduino. Please help. Many thanks.
