# Write Value
|
|
|
|
Write a name/value pair and a newline character (`\r\n`) to the [serial](/device/serial) port.
|
|
|
|
```sig
|
|
serial.writeValue("x", 0);
|
|
```
|
|
|
|
### Example: streaming data
|
|
|
|
Every 10 seconds, the example below sends the temperature and light level
|
|
to the serial port.
|
|
|
|
```blocks
|
|
basic.forever(() => {
|
|
serial.writeValue("temp", input.temperature())
|
|
serial.writeValue("light", input.lightLevel())
|
|
basic.pause(10000);
|
|
})
|
|
```
|
|
|
|
#### ~hint
|
|
|
|
The [send value](/reference/radio/send-value) function broadcasts
|
|
string/number pairs. You can use a second micro:bit to receive them,
|
|
and then send them directly to the serial port with ``write value``.
