Hello and nice day to all. i want to ask about my problem with this program. anyone can help me to solve this problem. im new to this arduino programming. thank you
Why do you have + and - in front of some of the statements?
I can't view your picture but if this is about the compiler complaining about stray characters, it's probably something that was copied from a website.
Except for properly editing the code which might be time consuming, you can try to start a post here, paste the code in it, click preview, copy the code from the preview and paste it in the sketch.
The picture you posted seems to be the output of a 'diff' showing the lines removed (-) and lines added (+) between two versions. Remove the lines that start with '-' and remove the '+' from the lines that start with '+'.
