Please READ THIS POST to help you get the best out of the forum.

SIMPLE TROUBLESHOOTING.

These steps may also save you some unnecessary time and effort in the forum.

Always provide as much detail as possible to your issue it may be important.
If applicable provide your SKETCH inside CODE TAGS ( </> ) or a CREATE share link.
If applicable provide a schematic even if hand drawn.
How to insert a picture into your post

COMMON ISSUES

Check you have a COMMON GROUND where required.
Where possible use USB 2.0 ports or a USB 2.0 POWERED HUB to rule out USB 3.0 issues.
Try other computers where possible.
Try other USB leads where possible.
You may not have the correct driver installed. CH340/341 or CP2102
There may be a problem with the board check your wiring first.
Remove any items connected to pins 0 and 1.
COMPUTER RELATED
Ensure you turn off any additional security / antivirus just to test.
There may be a problem with the PC try RESTARTING it.
You may be selecting the wrong COM port.
Avoid cloud/network based installations where possible OR ensure your Network/Cloud software is RUNNING.
Clear your browsers CACHE.
Close the IDE before using any other serial programs.
Preferably install IDE's as ADMINISTRATOR or your OS equivalent
Performing the above actions may help resolve your problem without further help.

Bob.

Please tell us where you got the library from. @spycatcher2k already asked for that.

pert · November 21, 2019, 9:58am

What gave you the idea that you should call ultrasonic.timing() in your sketch? Are you basing your code on an example sketch?

I've merged your cross posts @paulohsantos19.

Cross posting is against the rules of the forum. The reason is that duplicate posts can waste the time of the people trying to help. Someone might spend 15 minutes writing a detailed answer on this thread, without knowing that someone else already did the same in the other thread.

Repeated cross posting will result in a suspension from the forum.

In the future, please take some time to pick the forum section that best suits the topic of your question and then only post once to that forum section. This is basic forum etiquette, as explained in the sticky "How to use this forum - please read." post you will find at the top of every forum section. It contains a lot of other useful information. Please read it.

Thanks in advance for your cooperation.
