Jep. On elektron level the elektricity flows from negative to positive. BUT, when wi use it with circuits, an many components, it's easyer to think that electricity flows otherway. //sorry my english, from finland. Maeby I just shut up.
"Oddly enough, the direction of the diode symbol's “arrowhead” points against the direction of electron flow. This is because the diode symbol was invented by engineers, who predominantly use conventional flow notation in their schematics, showing current as a flow of charge from the positive (+) side of the voltage source to the negative (-). "
@Halthum You just went against what you were saying.
"Oddly enough, the direction of the diode symbol's “arrowhead” points against the direction of electron flow"
Hence electricity flowing from the cathode to the anode.
The symbol for a diode is that way because again the symbol was drawn up before it was widely known and accepted that electronics flow from the cathode to the anode.
Besides this rivalry, accept I'm right and lets be friends, please.
@chickenpoper We can still be friends, have this conversation, and this has nothing to do with a rivalry.
The first sentence explained why you are confused (odd naming convention), the second sentence explains that current flows from positive to negative. That is what your first post disputed.
My description on the link is correct "current to flow one way (anode [+] to cathode [-])" as it is supported by both your link and MIT's page.

@chickenpoper Thanks for your input. I can see where you get that idea, but any textbook (or Wikipedia on LEDs under the "Physics" section, first sentence) will tell you that current flows from the anode to the cathode. The labeling convention for circuit diagrams has current (or electrons) flowing from + to -. However, electrons do still have negative charge. XKCD comic 567 is on this exact topic.
@Halthum Edision had a 50/50 chance of getting "Which way electricity flows" right but go it wrong when he decided that electricity flows from pos to neg due to the water theorem of higher pressure to lower pressure. It was widely accepted until we were able to get a view at atoms. But in theory as electrons flow from negative to positive you could think of the anode becoming more negative and the cathode becoming more positive. The only reason it is still in books is because edisons
@Halthum theory was widely accepted for 100+ years. It takes time for ideas to change and evolve you know. Any electronics and physics teacher would agree with anything i have said(Accept electricians as they still believe in edisons theories).
And wikipedia is easily changeable by anyone so the last person that changed it wasn't thinking clearly.
@chickenpoper I put a link in the description to an MIT page about LEDs that says that "[LEDs] pass current only in one direction, from anode to cathode." It's in the first section on "What is an LED?".
@Halthum Okay then, no use in trying to win against someone as stubborn as a donkey :) Seriously, they are really stubborn!
But now lets talk about this, did you charlieplex the led's here because i don't see any shift registers here. Secondly, do you know if there is any c++ to arduino converters around? I have the arduino mega 2560 r3 and this micro controller and i would like to switch around the codes back and forth without having to rewrite it.
@Halthum By the way did you go to school for this? Coding? Electronics? Because again i have no idea where you got this crazy idea that electricity flows from positive to negative, you must be an electrician. How old are you?
@Halthum I'm not a troll at all, I'm just stubborn also :) I know i am 100% right and my electronics teachers can back me up 100% that electricity flows from negative to positive, why are you so stuck on believing otherwise? I would really like to know, I will never be a troll in any way. I'm a nice person, why would i want to be a troll, but seriously let's end this feud before it does come to be a rivalry. I dont like making enemies.
Nicely done. I'm wanting to do a project like this to get familiar with the code. I come from a Java background so I'm not too familiar with the C. Anyway I could get your source code for reference? devin123w@yahoo.com
@alokcom Message me your email, and I'll send you the code. As for schematic, I'll try to see what I can do. The comments in the source code should give you some explanation. Message me if you need any help.

Your description is wrong, electricity flows from negative to positive so it flows from the cathode to the anode.

@chickenpoper Current, not electricity.
Electricity is a more general term.
Current or (electric current) flows from + to -.
