I bought a kit online for the arduino uno. I just set up my first project ever with a potentiometer controlling the delay on blinking pin 13. I had an LED in there, and then decided to try to hook up a buzzer and LED in series and the brightness of the LED DROPPED. How am I supposed to do this?

General series circuit question (noob)

Mmm I think only the LED that's on the board has a resistor. I'd still use one.
