is there something like Serial.clear(); sorta or like a mod for arduino i am trying to make the serial monitor clear so it does not look like a mess and updates the stuff in it so i do not have 100msto see wut it means before it leaves
No, use a real Serial monitor/Terminal program. I use PUTTY for example.
can you send me a tutorial on how to i can't figure out how
Use a decent terminal program that supports ansi escape - Google Search codes.
Serial monitor is a primitive program. The only advantage that it offers is that it can be controlled by the IDE; the IDE closes the connection when you perform an upload and opens the connection again once the upload is finished.
