Why is my code only doing my void setup?

before adding thingSpeak the code was working normally however upon adding it, it begun to not read my void loop and only read my void setup again and again.
did I do something wrong?

Could be a power supply problem. The Arduino is resetting because of a voltage drop. Perhaps at the point where communications with thingspeak begins, the extra power/current required causes a voltage drop which resets the Arduino.

Insert some extra Serial.println("beginning/end of setup/loop") to figure out if that is true. Then insert more Serial.println("doing XYZ") at other points to narrow down where the reset is occurring.

Read the forum guide to find out what else you need to post so that forum members can help you diagnose the problem.

If the passwords and the likes are the real ones, I suggest that you edit your post and replace them by dummies (e.g. ***) when posting the code on the forum.

Include the entire error message. It is easy to do. There is a button (lower right of the IDE window) called "copy error message". Copy the error and paste into a post in code tags. Paraphrasing the error message leaves out important information.

Post a schematic.

Post an image of your project.

Which Micro Controller are you using?

Is this simulator code?

Make a new tab in your project. Call the tab MyThingsToKeepSeceret.h. Put your ssid and password into MyThingsToKeepSeceret.h, save. Add to the project an #include MyThingsToKeepSeceret.h, now we will not see your stuff.
