You have to be careful not to short that to ground, etc. You can permanently damage things, which I guess you may have already done :( | |

| Jan 13, 2015 at 2:52 | comment | added | goldilocks♦ | In your photo, you have 3.3 V direct to the LED then the resistor between the LED and ground. That's wrong -- as per your diagram linked here, the resistor should be between 3.3 V and the LED, then the LED is direct to ground. That probably won't prevent the LED from lighting up, but it may cause it to burn out... | |
