## Simple animation
|
|
|
|
Let's start by using a combination of [forever](/reference/basic/forever) and [show leds](/reference/basic/show-leds) to create animation:
|
|
|
|
```blocks
|
|
basic.forever(() => {
|
|
basic.showLeds(`
|
|
# # . # #
|
|
# # . # #
|
|
. # # # .
|
|
. # . # .
|
|
. # . # .
|
|
`)
|
|
basic.showLeds(`
|
|
. . # . .
|
|
. . # . .
|
|
# . . . #
|
|
# . # . #
|
|
# . # . #
|
|
`)
|
|
})
|
|
```
|
|
|
|
Download this code to your @boardname@ and try it out.

## Turn off animation in the pocket
|
|
|
|
If the wallet is in your pocket, you should turn off the LEDs to save energy.
|
|
|
|
How do we know that the wallet is in the pocket? It is really dark in there... We can use the [light level](/reference/input/light-level) to detect this!
|
|
|
|
Using an [if statement](/blocks/logic/if), we can test if the level of light is sufficient to turn on the screen. Otherwise, we turn off the screen for a few second to save energy.
|
|
|
|
```blocks
|
|
basic.forever(() => {
|
|
if (input.lightLevel() > 16) {
|
|
basic.showLeds(`
|
|
# # . # #
|
|
# # . # #
|
|
. # # # .
|
|
. # . # .
|
|
. # . # .
|
|
`)
|
|
basic.showLeds(`
|
|
. . # . .
|
|
. . # . .
|
|
# . . . #
|
|
# . # . #
|
|
# . # . #
|
|
`)
|
|
} else {
|
|
// clear screen and wait
|
|
basic.clearScreen()
|
|
basic.pause(3000)
|
|
}
|
|
})
|
|
``` |
