# Serial Write Line
|
|
|
|
Write a string to the [serial](/device/serial) port and start a new line of text
|
|
by writing `\r\n`.
|
|
|
|
```sig
|
|
serial.writeLine("");
|
|
```
|
|
|
|
## Parameters
|
|
|
|
* `text` is the [string](/types/string) to write to the serial port
|
|
|
|
## Examples
|
|
|
|
### Simple serial
|
|
|
|
Write the word `BOFFO` to the serial port repeatedly.
|
|
|
|
```blocks
|
|
basic.forever(() => {
|
|
serial.writeLine("BOFFO");
|
|
basic.pause(5000);
|
|
});
|
|
```
|
|
|
|
### Streaming data
|
|
|
|
Check the [compass heading](/reference/input/compass-heading) and show the direction on the screen. Also, send both the direction and degree heading to the serial port.
|
|
|
|
```blocks
|
|
let degrees = 0
|
|
let direction = ""
|
|
basic.forever(() => {
|
|
degrees = input.compassHeading()
|
|
if (degrees < 45) {
|
|
basic.showIcon(IconNames.ArrowNorth)
|
|
direction = "North"
|
|
} else if (degrees < 135) {
|
|
basic.showIcon(IconNames.ArrowEast)
|
|
direction = "East"
|
|
} else if (degrees < 225) {
|
|
basic.showIcon(IconNames.ArrowSouth)
|
|
direction = "South"
|
|
} else if (degrees < 315) {
|
|
basic.showIcon(IconNames.ArrowWest)
|
|
direction = "West"
|
|
} else {
|
|
basic.showIcon(IconNames.ArrowNorth)
|
|
direction = "North"
|
|
}
|
|
serial.writeLine(direction + " @ " + degrees + " degrees")
|
|
basic.pause(500)
|
|
})
|
|
```
