Hi community,

I was wondering if you can print a value of a variable in the console of the Arduino IDE?

Like in Java: System.out.println(myVar);

Thanks,

They're called Serial functions.

You call

Serial.begin(/*baud, generally 9600*/ 9600);

once (ie in setup)
and then

Serial.print(/*Number or string*/ "hithere");

to actually print.

To view the messages, you click the "serial monitor" button in the IDE, and make sure the bauds are the same.

No, but the rightmost icon opens the Serial Monitor, where Serial.print() and Serial.println() statements output data.
