Jesus Christ, I know I am a n00b when it comes to electronics, but why did it take me the whole day of reading tutorials and watching YouTube videos about the Raspberry Pi to find out what I was doing wrong? This video is the first one which mentions that it is important that the cathode of a LED has to be connected to the ground, not the other way around.

Classic. I'm actually doing alot with my RPi and leds + joystick. Trying to create an emulator-station out of it in haskell.
Anton Ekblad tipped on this fantastic package, HPi. Great usability.
So what are you trying to emulate?
NES, Snes mostly
So that the buttons and joystick i'v connected to the GPIO works as input.
I see, is it fast enough? And wouldn’t it be easier to connect the Joystick via USB?
Oh it's no problem with NES & Snes. The beauty of the project is to have an dedicated EMU-box made from RPi and a real joystick as input. The buttons are illuminated so you can play in the dark :D
Haha nice :D
Anode + katode -
the point of a diode is to let a current flow through the circuit in only one direction. this is what happens for example to alternating current https://dlnmh9ip6v2uc.cloudfront.net/assets/2/9/2/f/3/5176f4bfce395f3a61000000.png LED = light emitting diode
Hela grundiden med en diod :-)
