Hi guys,
I have a very beginner question.
For my RC car, I want to add 2 red LEDs and 2 white LEDs in to the car. I want to use 9V battery to avoid using 1.5V battery pack. Is there any way to have the circuit avoiding using resistor or do I have to use a resistor no matter what? I'd appreciate your guidance.
