If someone can help me i will be thankful

[lau0072]

So I posted the error log down below it's a program from school but I can't make it work and I'm very angry so i turned to forums for a solution i know the program works because at school i played with it but the version of Arduino was 1.8 if I'm not mistaken also thank you to everyone for reading this and for helping me in case of something i can also post the code here.

There is obviously a problem with the code that you did not post

The easier you make it to read and copy the code the more likely it is that you will get help

Please follow the advice given in the link below when posting code , use code tags and post the code here

How to get the best out of this forum

Hello, Welcome to the Arduino Forum. This guide explains how to get the best out of this forum. Please read and follow the instructions below. Being new here you might think this is having rules for the sake of rules, but that is not the case. If you don’t follow the guidelines all that happens is there is a long exchange of posts while we try to get you to tell us what we need in order to help you, which is frustrating for you and frustrating for us. The people who try to help with your pro…

Ouch.

My poor scrolling finger.

[lau0072]

Sorry I'm still new to this so yeah now I'm trying to post my small code

[lau0072]

So someone suggested to me to post my code, it's small but it caused me a lot of headache and still it doesn't worl

When I asked you to post your code I also suggested that you use code tags when doing so and provided a link to advice on how to do it

Did you deliberately ignore that advice and where is the rest of your code ?

[lau0072]

Idk how to use tags it's first time posting here and I believed this is whole like code but I was wrong didn't saw that it doesn't include everything like my code is structured in different functions which I swap in another loop each time I want something different.

[sterretje]

The simplest way is to use edit->copy for forum in the IDE and next paste it in a reply.

And you should read the link in post #2

[missdrew]

Also, don't use the windows app version of the IDE, it is buggy & old. Download the current version from here.

The good news for a beginner, is that when your code generates pages of errors like this, - the problem is usually very fundamental - in only one or two important places.

The compiler simply can’t figure our what you’re trying to do, hence when it tries to understand your code, it goes looking for references…. and fails.
