Unless you're an *experienced* electronics hobbyist, BEFORE you connect you Arduino / project to anything other than the USB cable... understand these things.

Read up and understand these concepts.
   -  Voltage (V) both DC / AC
   -  + / - voltages
   -  Current (I)
   -  Power (dissipation). (W)
   -  Vin / Vcc. 5V / 3.3V
   -  The importance of Ground / 0V
   -  Drivers - to separate your *load* from the Arduino pins.

Failing to do so will - almost certainly - eventually end in tears, and a new Arduino or interface board.
Experienced responders have a nose for laziness, (they were beginners once)... Sure, there are trolls, chest-beaters, and pretenders - but the help you'll get here is about as good as it gets - if you try to help youself!.
