I'm trying to power my arduino and L298N from a single supply.
The L298N board has a 5v out which others have said CAN be used to power the arduino. However, i've found that the supply I'm using (12v 2A DC into the L298N) doesn't supply enough current to the arduino to keep it alive when the stepper motor is running. I also have an LCD screen running from the arduino along with a strain guage, the LCD screen is dim (compared to when I power the arduino via USB).
I realise i may need to buy a different power supply. My electronics knowledge is not strong, how can I power both boards from the same power supply without overloading either?
