Pin Number?

I have an Arduino mega2560 board. The sketch I load for BLINK, sets pin 13.

But on the schematic, it says pin 26.

Why?

Blink was probably written for a Uno type board that has the onboard LED on pin 13.

The LED is blinking.

Board pin numbers do not correspond with chip pin numbers. Also it is processor dependent.

Now make it blink without using delay().

Hi,

I have a question about How can I read data of website by Arduino.

Thank you

Why is my LED blinking?

You said you loaded the blink code. That's what it does.

If this is the quality of help here, maybe I should consider a different board.

Is there anyone here who has a clue of what I'm asking?

See reply #3. If you measure the voltage on pin 13, you will also see it toggle as the LED blinks.

The pins have two (or more) names. The physical chip pin and the name the pin is known by in the IDE. The pin 13 in the IDE is the physical chip pin 26 (on the 2560 19 on a mega 328) . Like aarg was saying.

Chill out! Your question WAS answered in the third reply.

If that is true, is there a real IDE that will work with this board?

Probably not, so give your board to some school kids and get another hobby.
