# Level
## Is it level? @unplugged
Is your table flat? Use the @boardname@ as a level!
## {Step 1}
Make a variable ``||variables:x||`` and store the ``||input:acceleration x||`` value
in the ``||basic:forever||`` loop.
```blocks
basic.forever(function() {
// @highlight
let x = input.acceleration(Dimension.X);
})
```
## {Step 2}
Make another variable ``||variables:y||`` and store the ``||input:acceleration y||`` value.
```blocks
basic.forever(function() {
let x = input.acceleration(Dimension.X);
// @highlight
let y = input.acceleration(Dimension.Y);
})
```
## {Step 3}
Add a code to test ``||logic:if||`` the ``||Math:absolute value||`` of ``||variables:x||`` is ``||logic:greater than||`` ``32``.
If it is true, ``||basic:show an icon||`` to tell you that the @boardname@ is not flat, ``||logic:else||`` show nothing, for now.
```blocks
basic.forever(function() {
let x = input.acceleration(Dimension.X);
let y = input.acceleration(Dimension.Y);
if (Math.abs(x) > 32) {
// @highlight
basic.showIcon(IconNames.Sad)
} else {
}
})
```
## {Step 4}
Add an ``||logic:else if||`` to check that the ``||Math:absolute value||`` of ``||variables:y||`` is ``||logic:greater than||`` ``32``.
If it is true, ``||basic:show an icon||`` that tells you the @boardname@ is not flat.
```blocks
basic.forever(function() {
let x = input.acceleration(Dimension.X);
let y = input.acceleration(Dimension.Y);
if (Math.abs(x) > 32) {
basic.showIcon(IconNames.Sad)
} else if (Math.abs(y) > 32) {
// @highlight
basic.showIcon(IconNames.Angry)
} else {
}
})
```
## {Step 5}
The code under the ``||logic:else||`` will run if both acceleration ``x`` and ``y`` are small, which happens when the @boardname@ is laying flat. Add code to ``||basic:show a happy image||``.
```blocks
basic.forever(function() {
let x = input.acceleration(Dimension.X);
let y = input.acceleration(Dimension.Y);
if (Math.abs(x) > 32) {
basic.showIcon(IconNames.Sad)
} else if (Math.abs(y) > 32) {
basic.showIcon(IconNames.Angry)
} else {
// @highlight
basic.showIcon(IconNames.Happy)
}
})
```
