@yjhdhmkij, your topic has been moved to a more suitable location on the forum. Installation and Troubleshooting is not for problems with your project :wink: See About the Installation & Troubleshooting category.

Can you please provide the full error message; there should be a button "Copy error messages" in the orange bar when compilation fails. Click it and next paste here in a reply.

i cant change location

What does that mean? If you want to move the topic, that's already done. If something else, please elaborate.

This Is The Error

C:\Users\Admin\Downloads\led\led.ino: In function 'void setup()':

led:100: error: expected initializer before '.' token

const char WiFi.begin ("ssid, password");


exit status 1
expected initializer before '.' token

i changed the topic

Lose the "const char"

It's still / again in the wrong section :wink: Installation and Troubleshooting is not for problems with your project :wink: See About the Installation & Troubleshooting category.


It's again in the wrong category. I will move it, please leave it where I put it.
