# Streaming
|
||
|
|
|
||
|
|
This page describes how to stream data from the micro:bit to the editor or even to the cloud.
|
||
|
|
|
||
|
|
## Before starting...
|
||
|
|
|
||
|
|
Make sure you follow the instructions on [how to setup a serial connection](/device/serial) with the micro:bit.
|
||
|
|
|
||
|
|
## A typical scenario
|
||
|
|
|
||
|
|
A common scenario is to chart some sensor data, such as the acceleration, and analyse it in the editor.
|
||
|
|
For example, run this code on your micro:bit.
|
||
|
|
|
||
|
|
```blocks
|
||
|
|
basic.forever(() => {
|
||
|
|
led.plotBarGraph(input.acceleration(Dimension.X), 0);
|
||
|
|
});
|
||
|
|
```
|
||
|
|
|
||
|
|
If your serial connection is working, you will start to see a chart representing that acceleration ``x`` value read from the micro:bit.
|
||
|
|
Each time ``led.plotBarGraph`` is called, the value is also written to the serial output. The log view automatically detects
|
||
|
|
that there is a data stream and displays a graph.
|
||
|
|
|
||
|
|
## Local download
|
||
|
|
|
||
|
|
The log view will automatically start to collect and organize the data it detects. Simply click on the log view to open the various options
|
||
|
|
to export the data. The simplest option is to download the data as a **CSV file**. This file can easily be opened in programs like Office Excel.
|
||
|
|
|
||
|
|
## Cloud upload
|
||
|
|
|
||
|
|
In the data export dialog, there is another option to upload the data to the cloud. This allows to upload small amounts of data
|
||
|
|
without any kind setup. The data can be accessed via web services or directly from Office Excel.
