So im trying to make rgb light controlled from a website, ive went back and fourth with chatgpt but its not helping, it was working for a while but now i cant upload because its giving me this error code: avrdude: ser_open(): can't set com-state for "\.\COM7"
Failed uploading: uploading error: exit status 1 PLEASE FOR GODS SAKE SOMEBODY HELP ME ive been at chatgpt for 5 HOURS i didnt sleep last night PLEASE SOMEBODY HELP ME.
Post here your full code (enclose it with "<CODE/>" tags), the board type you're using (UNO? Nano? Mega?...) and specify if you have something connected to any Arduino pins while uploading (especially if you're using pins D0 and/or D1, disconnect weverything before uploading).
And please, please: stop using that bl**dy ChatGPT because if you rely 100% on it, you won't understand what you're doing and you won't learn a thing. Start studying Arduino coding, then use ChatGPT just as a quick start, but it won't give you every time full working code, especially if you need to change something.
Meaning "no pain, no gain". Or "there ain't no such thing as a free lunch"
See if Port monitor error: command 'open' failed: Invalid serial port. Could not connect to COM serial port - #49 by ptillisch helps you.
