println() like in processing to check values?

Hey guys,

is there any possibility to display var values without having connected my arduino to the usb port? I am just experimenting with some mathematical operations i will need later on for my arduino project. So I just want to check some values.

Just like println() in processing. Serial.print() didnt work without having connected my Arduino.

I didnt find any information about my problem in this forum. And sry for my bad english. :slight_smile:

If you want to display values of variables, you will need a display device, and that display device will need to be connected to the Arduino. So, you can use the PC's screen when the Arduino is connected to the PC, or you can use, say, an LCD when that LCD is connected to the Arduino. Do you have an LCD? Or maybe a LED display? If so, you can use that to display variable values.
