Hello,

See:

> [@Problem i face in serial communication](https://discourse.processing.org/t/problem-i-face-in-serial-communication/17023/2):

> Hello, You receive a string which includes a newline character ( ‘\n’ ) You need to remove the newline character ( ‘\n’ ) that is in the received string before splitting it so you can convert to an int. Example: [https://processing.org/reference/trim\_.html](https://processing.org/reference/trim_.html)[https://processing.org/reference/String.html](https://processing.org/reference/String.html) (discusses newline character and escape sequences such as \n) slight_smile String s1 = "123,456,890\n"; String [] list1 = split(s1, ','); printArray(list1); println(int(list1[2])…
