Hi everyone,
I’m new to Arduino and robotics. I’m currently building a flywheel project using an Arduino Uno R3, an L298N motor driver, and a DC motor.
My setup is powered by a 12V wall adapter plugged directly into the Arduino’s DC barrel jack.
When I want to update or change my code via USB, do I need to completely disconnect the 12V power and the L298N wiring, or is it safe to keep everything plugged in while the Arduino is connected to my computer? I want to avoid frying my board or my USB port.
Any advice on the best workflow for frequent code iterations would be appreciated!
