Setting up: problem

Community General Discussion

I am following the arduino UNO book. I have tested the blink sketch. It was

  1. successfully uploaded - said done uploading,
  2. I didnt mess up the ports - i also tried all other ports,
    so I am confused as to why tx and rx leds are still not blinking when I uploaded it. Other than that, I have tested the sketch with different values and the pin 13 LED does not change the frequency at which it's blinking - it stays at the same rate. pls help :(

My first guess would be that you did not follow the instructions correctly.

Your blink.ino sketch will make the "L" LED blink. The Tx and Rx LEDs should only blink to reflect activity on pins 0 and 1, like when you upload the sketch, or print to the Serial Monitor.

Your blink rate is determined in your code/sketch.

the L LED doesnt change the rate after i changed the code thats why im worried, although it said it was successfully compiled

Do u have any idea where I couldve messed up? i reread it again and again and I just have no clue.

Upload the new code.

The IDE arrow is upload.
The IDE checkmark is only to verify code syntax.

th rx tx leds dont blink either way, even when i upload a new sketch. It does say in the book some arduinos come with blink sketch preuploaded but i have tried with other sketches and I still havent noticed them blinking

i did

Yes, they do, during upload or print.

Since you haven't shown us what you did, no one has any idea what you did wrong.

The only thing I can say with certainty is that you didn't follow the instructions. Not in doing your sketch, nor in posting in this forum.

How to get the best out of this forum

thank you

sorry was my first time here, didnt even see any instructions to posting. my bad

14

I thought everyone signing up had to go through a bunch of procedures, mainly posting, with some rules to follow.

16

im sorry :( literally my first time in any forum ever

You will figure it out. Read the link. Have fun.

It's easy to identify which port you should be using. It's the port that disappears when you unplug the Arduino and reappears when you plug the Arduino back in again.

Hi @anon5635620
Are you using a genuine Arduino Uno R3?

20

Yes. I figured out with the help of previous comments that it is the arow in the IDE that i was confused about, i was verifying the code instead of uploading. Thank you nonetheless

21

Yes. It is indeed easy.
