# Write Line
|
||
|
|
|
||
|
|
Writes a string and a new line character (`\r\n`) to [serial](/device/serial).
|
||
|
|
|
||
|
|
```sig
|
||
|
|
serial.writeLine("");
|
||
|
|
```
|
||
|
|
|
||
|
|
### Example: streaming data
|
||
|
|
|
||
|
|
The following example constantly checks the [compass heading](/reference/input/compass-heading) and sends the direction to serial.
|
||
|
|
|
||
|
|
```blocks
|
||
|
|
basic.forever(() => {
|
||
|
|
let heading = input.compassHeading()
|
||
|
|
if (heading < 45) {
|
||
|
|
serial.writeLine("N");
|
||
|
|
} else if (heading < 135) {
|
||
|
|
serial.writeLine("E");
|
||
|
|
}
|
||
|
|
else if (heading < 225) {
|
||
|
|
serial.writeLine("S");
|
||
|
|
}
|
||
|
|
else {
|
||
|
|
serial.writeLine("W");
|
||
|
|
}
|
||
|
|
})
|
||
|
|
```
|
||
|
|
|
