 Hooking up an LED without a resistor isn't necessarily damaging because of the 3.3v, but instead the unrestricted current: Hooking up an LED without a resistor isn't necessarily damaging because of the 3.3v, but instead the unrestricted current:
  
-using Ohm's law: V = I * R, where 'I' is current/amperage:+using Ohm's law: V = I * R, where 'V' is voltage (measured in volts), 'I' is current/amperage (measured in amperes), and 'R' is resistance (measured in Ohms):
  
-I = V / R+**I = V / R**
  
 I = 3.3 / 1 (there's some inherent resistance on the conductor itself, plus, we cannot divide by 0) = 3.3 I = 3.3 / 1 (there's some inherent resistance on the conductor itself, plus, we cannot divide by 0) = 3.3
