For the Arduino kit project I created a circuit that would light up an LED if the button was pressed and could be dimmed by a potentiometer only when the button was held down. I also added on a stepper motor which didn’t seem to work simultaneously with the LED. I believe there is either not enough power for all the components or my code is making the stepper motor a priority over the LED.
