Serial Monitor in Programer

I have just started back doing some programing I am mostly familiar with Basic but wanting to learn more about C++

My problem is I am running a program to read analog input signals from a thermister to read temperatures to Serial Monitor, when it reads temps it scrolls all the way down the screen as it updates I would like it to only print the temperature on first line as it is updated, I am using println

You'll need another terminal program then. The serial monitor that comes with the Arduino IDE is pretty basic. There's not any way to do what you want with it.

Thanks, do you recommend another program?

Change your sketch so that it doesn't do the println so often.

The terminal program puTTY works on most PCs
