WebMay 6, 2024 · The arduino has it’s own 5V regulator. The L298 has a motor voltage input. The arduino has an external dc voltage barreljack. Since you stated you have little electronics experience, allow me to clarify this issue for you. If you have TWO 5 V regulators, it is best to use them both. Run the L298 from the dc motor Vin and run the … WebThe Vin, 5V, 3.3V, and GND pins are Arduino power pins. You can use the Vin pin to Power your Arduino with an unregulated 7 to 12-volt power source. Like a 9V battery or a wall adapter that is in the range of 7 to 12 volts. Alternatively, you can power your Arduino through the 5V pin with an external regulated 5V power supply.
