Port not recognized

[JohnRob]

For any useful feedback we need:

1. Schematic
2. Better explanation of the issue. "Everything works fine...." However you also worded it to suggest the ultrasonic sensor was not connected.

How to make a schematic you can post.

When you submit a question on the forum you will usually need to add a schematic (circuit diagram). The tutorial that follows will explain some ways to create a useful image; however lets start by explaining how to add the image to your post. Its easy. Having created the image all you need to do is : Save the image somewhere convenient - maybe your desktop Start your post, and place the cursor (insertion point) where you want the image to be shown; [upload image to forum] 3: click th…

Hi,
Some pictures of your project would help, so we can see your component layout.

Thanks.. Tom...

I have merged your cross-posts @phantom_20.

Cross-posting is against the Arduino forum rules. The reason is that duplicate posts can waste the time of the people trying to help. Someone might spend a lot of time investigating and writing a detailed answer on one topic, without knowing that someone else already did the same in the other topic.

Repeated cross-posting can result in a suspension from the forum.

In the future, please only create one topic for each distinct subject matter. This is basic forum etiquette, as explained in the "How to get the best out of this forum" guide. It contains a lot of other useful information. Please read it.

Thanks in advance for your cooperation.

Thanks guys for the help. It started working

@phantom_20

It started working

It would be useful if you posted what was actually wrong and how it was solved. Some might try a similar project and run into the same issue.

Ok then, well, my breadboard has 30 terminals so in my attempt where it was not working I put it the ultrasonic sensor pins at a1,b1, c1 and d1. However this had not worked so I put it the other way around near the 15 mark area and when I connected the gnd to the negative terminal of the breadboard my project started working fine. Not sure what was the issue.

[phantom_20]

15 mark area meaning it was perpendicular to the other one

@phantom_20

Not sure what was the issue

In a numbered column, all pins are connected as shown below. So yes, Vcc and GND in the same numbered column will cause a short.

                    1 1 1
  1 2 3 4 5 6 7 8 9 0 1 2

HI,
Can you please post some images of your project in the breadboard?

See post #24.

Thanks.. Tom..

[phantom_20]

Ohk thx for clearing that

[phantom_20]

Yeah I'll send it a bit later

[phantom_20]

Apologies for the late reply

[phantom_20]

When I put it like this the problem was fixed but if you put it perpendicular that's when it gets short.
