# temperature activity

|
|
Measure the temperature on the micro:bit
|
|
|
|
To create a new script, go to the [Create Code](/create-code) page and tap `New Project` under `Block Editor`.
|
|
|
|
Welcome! This activity will teach how to measure the temperature on the micro:bit. Let's get started!
|
|
|
|
We want to display the temperature on shake. In order to do so, we need to register the event `on shake` that will execute whenever the user shakes the micro:bit; in the web browser, click the button labelled "SHAKE" under the simulator to generate a shake event
|
|
|
|
```blocks
|
|
input.onGesture(Gesture.Shake, () => {
|
|
|
|
})
|
|
```
|
|
|
|
Let's measure the temperature and then store in it a variable `temp`. The temperature is measured in **Celsius**, so a value of `29` is equivalent to 29 degrees Celsius.
|
|
|
|
|
|
```blocks
|
|
input.onGesture(Gesture.Shake, () => {
|
|
let temp = input.temperature()
|
|
})
|
|
```
|
|
|
|
Show the value of `temp` on the screen.
|
|
|
|
```blocks
|
|
input.onGesture(Gesture.Shake, () => {
|
|
let temp = input.temperature()
|
|
basic.showNumber(temp)
|
|
})
|
|
```
|
|
|
|
* click run to see if the code works as expected.
