```
## Example: compass
You can have part of a program continuously by placing it in an **forever** loop. The **forever** loop will _yield_ to the other code in your program though, allowing that code to have time to run when needs to.
### ~ reminder
#### Event-based loops
Both the **forever** loop and the **every** loop are _event-based_ loops where the code inside is run as part of a function. These are different from the [for](/blocks/loops/for) and [while](/blocks/loops/while) loops. Those are loops are part of the programming language and can have [break](/blocks/loops/break) and [continue](/blocks/loops/continue) statements in them.
You can NOT use **break** or **continue** in either a **forever** loop or an **every** loop.

## Parameters
* `leds` is a [string](/types/string) that shows which LEDs are on and off, in groups one after another.
* `interval` is an optional [number](/types/number). It means the number of milliseconds to pause after each image frame.

# Bluetooth On UART Data Received
Registers an event to be fired when one of the delimiter is matched.
Runs some code in an event when a delimiter is matched in the received data.
```sig
bluetooth.onUartDataReceived(",", () => {})
bluetooth.onUartDataReceived(serial.delimiters(Delimiters.NewLine), function() {})
```
## Parameters
* `delimiters` is a [string](/types/string) containing any of the character to match
* **delimiters**: a [string](/types/string) containing the delimiter characters to match in the received data.
### ~ hint
#### Delimiters
Delimiters are characters in a received data string which divide the string into smaller strings to form separate data items.
Although multiple delimiter characters can be set in the **delimiters** string, it is common to have received data separated using just one delimiter character, such as a comma:
``"data1,data2,data3,data4"``
So, you can specify a delimiter character using the ``||serial:serial delimiters||`` which create a single character delimiter string for you...
```block
bluetooth.onUartDataReceived(serial.delimiters(Delimiters.Comma), function () {
})
```
Or, maybe...
```block
let delim = serial.delimiters(Delimiters.NewLine)
basic.showString(bluetooth.uartReadUntil(delim))
```
### ~
## Example
Read values separated by `,`:
Read the data items separated by a comma (`,`):
```blocks
bluetooth.onUartDataReceived(serial.delimiters(Delimiters.Comma), () => {
basic.showString(serial.readUntil(serial.delimiters(Delimiters.Comma)))
bluetooth.onUartDataReceived(serial.delimiters(Delimiters.Comma), function () {
basic.showString(bluetooth.uartReadUntil(serial.delimiters(Delimiters.Space)))
})

# change (Sprite Property)
Change the kind of [number](/types/number) you say for a [sprite](/reference/game/create-sprite).
Change a value for a [sprite](/reference/game/create-sprite) property by some amount.
```sig
game.createSprite(0,0).change(LedSpriteProperty.X, 0);
```
The value of a sprite propery is changed by using either a positive or negative number. Giving `1` will increase a property value by `1` and giving a `-1` will decrease it by `1`.
## Parameters
* **property**: the property of the **Sprite** you want to change, like:
>* ``x`` - how far up or down the sprite is on the screen (`0`-`4`)
>* ``y`` - how far left or right the sprite is on the screen (`0`-`4`)
>* ``direction`` - which way the sprite is pointing (this works the same way as the [turn](/reference/game/turn) function)
>* ``brightness`` - how bright the LED sprite is (this works the same way as the [brightness](/reference/led/brightness) function)

# Button event
Returns the ID of one of these button event types:
* Pressed Down (1)
* Released Up (2)
* Clicked (3)
* Long clicked (4)
* Hold (5)
This block can be used to define the event type in [on button event](input/on-button-event) and [on pin event](input/on-pin-event).
Note, that by pressing a Button multiple events can raise at the same moment:
| # | User input | Event raised |
|---|--------------------------|--------------|
| 1 | Press A down | A.Down |
| 2 | Hold A for > 1.5 seconds | A.Hold |
| 3 | release A | A.Up |
| | | A.LongClick |
| # | User input | Event raised |
|---|--------------|--------------|
| 1 | Press A down | A.Down |
| 2 | Press B down | B.Down |
| 3 | | A+B.Down |
| | Release A up | A.Up |
| | | A+B.Up |
| | | A+B.Click |
| | Release B up | B.Up |
* Every Up-Event will always be followed by either a Click- OR Long-Click-Event, depending on how long the Down-Event has been ago.
## Pressed Down
* For button `A` or `B`: This handler works when the button is pushed down.
* For `A` and `B` together: This handler works when `A` and `B` are both pushed down, at the moment the second button is pressed.
## Released Up
* For button `A` or `B`: This handler works when the button is released up.
* For `A` and `B` together: This handler works at the moment the first button is released up while `A` and `B` are both pushed down.
## Clicked
* For button `A` or `B`: This handler works when the button is pushed down and released within 1 second.
* For `A` and `B` together: This handler works when `A` and `B` are both pushed down, then one of them is released within 1.5 seconds of pushing down the second button.
## Long clicked
* For button `A` or `B`: This handler works when the button is pushed down and released after more than 1 second.
* For `A` and `B` together: This handler works when `A` and `B` are both pushed down, then one of them is released after more than 1.5 seconds after pushing down the second button.
## Hold
* For button `A` or `B`: This handler works when the button is pushed down and hold for 1 second.
* For `A` and `B` together: This handler works when `A` and `B` are both pushed down and hold for 1.5 seconds after pushing down the second button.

# set Sound Threshold
Tell how loud it should be for your board to detect a loud sound.
```sig
input.setSoundThreshold(SoundThreshold.Loud, 0)
```
When the microphone hears a sound, it sets a number for how loud the sound was at that moment.
This number is the sound level and has a value from `0` (low sound) to `255` (loud sound). You can use
a sound level number as a _threshold_ (just the right amount of sound) to make the
[on sound](/reference/input/on-sound) event happen. To set a threshold, you choose the type of sound
to detect, `loud` or `quiet`, and then the sound level for that type.

# every Interval
Run part of the program in a loop continuously at a time interval.
```sig
loops.everyInterval(500, function () {})
```
If you want to run some code continuously, but on a time interval, then use an **every** loop. You set the amount of time that the loop waits before the code inside runs again. This is similar to a [forever](/reference/basic/forever) loop, in that it runs continuously, except that there's a time interval set to wait on before the loop runs the next time. This loop is useful when you want some of a program's code run on a _schedule_.
## Parameters
* **interval**: a [number](/types/number) that is the amount of time in milliseconds to wait before running the loop again.
### ~ reminder
#### Event-based loops
Both the **every** loop and the **forever** loop are _event-based_ loops where the code inside is run as part of a function. These are different from the [for](/blocks/loops/for) and [while](/blocks/loops/while) loops. Those are loops are part of the programming language and can have [break](/blocks/loops/break) and [continue](/blocks/loops/continue) statements in them.
You can NOT use **break** or **continue** in either an **every** loop or a **forever** loop.
### ~
## Example
At every `200` milliseconds of time, check if either the **A** or **B** button is pressed. If so, show on the screen which one is pressed.
```blocks
loops.everyInterval(200, function () {
if (input.buttonIsPressed(Button.A)) {
basic.showString("A")
} else if (input.buttonIsPressed(Button.B)) {
basic.showString("B")
} else {
basic.clearScreen()
}
})

# random Boolean
Returns a pseudo-random boolean value that is either `true` or `false`.
```sig
Math.randomBoolean()
```
## Returns
* a pseudo-random [boolean](types/boolean) that is either `true` or `false`.
### ~ hint
#### What is pseudo-random?
Random numbers generated on a computer are often called pseudo-random. This because the method to create the number is based on some starting value obtained from the computer itself. The formula for the random number could use some amount of mathematical operations on a value derived from a timer or some other input. The resulting "random" number isn’t considered entirely random because it started with some initial value and a repeatable set of operations on it. Therefore, it’s called a pseudo-random number.
A random boolean is created by choosing a [random int](/reference/math/randint) ranging from `0` to `1`.
### ~
## Example
Make your @boardname@ do a coin toss when it's dropped softly. Have the LEDs show 'heads' or 'tails' as the result of the toss.
```blocks
input.onGesture(Gesture.FreeFall, () => {
if (Math.randomBoolean()) {
basic.showIcon(IconNames.Happy)
} else {

}

# create Sound Effect
Create a sound expression string for a sound effect.
```sig
music.createSoundEffect(WaveShape.Sine, 2000, 0, 1023, 0, 500, SoundExpressionEffect.None, InterpolationCurve.Linear)
```
A sound expression is set of parameters that describe a **[Sound](/types/sound)** that will last for some amount of time. These parameters specify a base waveform, frequency range, sound volume, and effects. Sound data is created as a [Sound](/types/sound) object and can then be [played](/reference/music/play-sound-effect) to the speaker, headphones, or at an output pin.
## Parameters
* **waveShape**: the primary shape of the waveform:
>* `sine`: sine wave shape
>* `sawtooth`: sawtooth wave shape
>* `triangle`: triangle wave shape
>* `square`: square wave shape
>* `noise`: random noise generated wave shape
* **startFrequency**: a [number](/types/number) that is the frequency of the waveform when the sound expression starts.
* **endFrequency**: a [number](/types/number) that is the frequency of the waveform when the sound expression stops.
* **startVolume**: a [number](/types/number) the initial volume of the sound expression.
* **endVolume**: a [number](/types/number) the ending volume of the sound expression.
* **duration**: a [number](/types/number) the duration in milliseconds of the sound expression.
* **effect**: an effect to add to the waveform. These are:
>* `tremolo`: add slight changes in volume of the sound expression.
>* `vibrato`: add slight changes in frequency to the sound expression.
>* `warble`: similar to `vibrato` but with faster variations in the frequency changes.
* **interpolation**: controls the rate of frequency change in the sound expression.
>* `linear`: the change in frequency is constant for the duration of the sound.
>* `curve`: the change in frequency is faster at the beginning of the sound and slows toward the end.
>* `logarithmic`: the change in frequency is rapid during the very first part of the sound.
## Returns
* a [sound](/types/sound) expression [string](/types/string) with the the desired sound effect parameters.
## Example
Create a sound expression string and assign it to a variable. Play the sound for the sound expression.
```blocks
let mySound = music.createSoundEffect(WaveShape.Sine, 2000, 0, 1023, 0, 500, SoundExpressionEffect.None, InterpolationCurve.Linear)

### ~
Normally the output signal level at the audio pin is `0` when no sounds are playing. This is the silence level and it stays constant since actual tones have varying levels over a period of time. Some devices (headphones, external speakers, etc.) which are sensitive to slight signal changes might play sounds from signal noise encountered along the connection between the audio pin and the audio device.
To reduce the effect of this signal noise it can be helpful to set an constant signal level for silence that is greater than `0`.
## Parameters
* **level**: a [number](/types/number) between `0` and `1024` to use as the silence level for the audio pin output when no sounds are playing. The default level is `0`.
## Example #example
Set silence level to `512` for the current audio pin.
```typescript

Find how strong the ``radio`` signal is, from `-128` to `-28`.
(`-128` means a weak signal and `-28` means a strong one.)
The @boardname@ finds the signal strength by checking how strong it was
the last time it ran the
[on received number](/reference/radio/on-received-number) function. That means
it needs to run **receive number** first.
## Returns

Measurement of the received signal strength is dependent on what version of @boardname@ you have. The @boardname@ boards prior to v2 can typically measure a signal strength up to `-42` dBm. Now, v2 boards will measure a signal strength up to `-28` dBm (typical).

If you haven't set a radio group for the @boardname@, it will use one selected randomly. If you are transmiting data to a @boardname@ that has a different hardware version from the sending @boardname@, it will select a random default group that is not the same as the other @boardname@.

**Pause for more data**
If the desired number of characters are available, **readBuffer** returns a buffer with the expected size. If not, the calling fiber (the part of your program calling the **readBuffer** function) sleeps until the desired number of characters are finally read into the buffer.
The need to pause for more data is set by the @boardname@ **[serial mode](https://lancaster-university.github.io/microbit-docs/ubit/serial/#serial-modes)**.
