Dont use the String class on small micro-controllers , there is NOTHING wrong with having evlines of code, it alls ends up in the serial buffer and won’t print faster... you are just using more memory than needed which can come bite you later... stick to 3 print...

Good morning J-M-L, The post does not say it wrong or right, it teaches another way to write the code. Thankyou for your consideration, they are very relevant.

If you compare program size with 3 line (classic output) and 1 line (with String class converting) you will be wonder. Your code add about 900 bytes.

you can use: Serial.printf(" Contando : %d Segundos \ ",x); //same line

Can the x++ also be incorporated into that line?

Friend SECURED4TEP yes, you can to use x++ incorporated in the Serial.print.

well explained article serial plot is also a good way to represent data in graph must check https://electronicsmith.com/arduino-serial-print/

Lembrando que concatenação de String's consome muita memória de seu Arduino, não aconselho usar este recurso sem um fim especifico como regra geral, tvz por isso não tenha na página de referencias oficial do Arduino.

Friend Rafael, good afternoon, i tested it here, it display this error: 'class HardwareSerial' has no member named 'printf'
