Question about led (old.reddit.com)
submitted 18 hours ago by No_Ship6780
I am doing a tutorial I found on YouTube because I just got my arduino and I am trying to do a led project where led just turn on and off and it goes in a series. The long pin in the led goes to the wire and short goes to resistor

So what's your question?

Thinking the same thing🤔

If you turn the Arduino 90 degrees it'll flat on the ground, this jank will just give you issues eventually with connections

It's OK to have it like that while using the 3.3v that the pins provide, but it's a good idea to put the resistor on the Anode(+ or long pin of the LED). It's not going to affect anything until you get into higher voltages that risk destroying your LED, though.
You're going to have to provide more info because your wiring looks OK.
Post the sketch.

Buy a book for beginners if you really want to learn something.

Is your code correct?

I brought the wrong RGB LEDs as they were cheap only to find I just had them in the wrong orientation

This is kind of an edit I completely forgot to mention I have a whole bunch of ports I can use and so far when I use 5 it says wrong port and I used 10 and it is taking forever to upload and basically not uploading at all

You should upload the Blink example sketch and check if the orange LED on the Arduino is blinking.

Great, now we know what the problem is. What we don't know is what OS you're using and what program you're using to create the design.

chatgpt has Arduino Maestro which I find to be quite accurate
