Zero to Arduino

The Arduino Gets 2 LEDs

  • Hooked up 2 LEDs
  • At first the second LED wasn't producing much power so I went off to debugging. 
  • Speculated that the resistor wasn't powerful enough. That wasn't the case. 
  • Speculated the pin wasn't powerful enough. That wasn't it either. 
  • Found out that I didn't set the pinMode on the pin my led2 was connected to. That was it! 
  • Decided that a morse code SOS signal would be fun to see blink up.
