i dont understand about transitors, can someone tell about it. and sending me an image to explain it to me better

Why is a question about transistors a poll?

I speak for myself, not Arduino.

Why a video, they don't move:-

Try and google for transistor lab videos, there are lots but actually reading about them is so much better.

ok,
so if im right, transistors are who get electric current from the E,
multiplis the energie from B,
and continue the circuit to C.

am i right?

I could print the Arduino logo on a box of cereal and sell it as "Arduin-O's"

Well if you think of current flowing from positive to negative then this is the wrong way round. However, if you think about the direction electrons flow this is right.

A transistor doesn't generate current but allows a small current flowing in the base to emitter, to control a much larger current flowing from collector to emitter.

I don't remember EVER seeing a legitimate "poll" on this website.

We did have one on removing karma, that was the only one I have seen that was a real poll.

ok, i connected the ground to the E,
then i connected a 5v to the B,
i continued the circuit of the grounds to C, hooking it up with an LED,
and finally connected the pin 13 to the other pin of the LED.

and its totally normal, nothing changed.
should it do somthing

No the cinfiguration will do nothing apart from blow up the transistor. What were you expecting it to do?
