# Using Touch Sensor Values
|
|
|
|
## Introduction @fullscreen
|
|
|
|
Use the Touch sensor value to stop a running motor.
|
|
|
|
|
|
|
|
## Step 1
|
|
|
|
Open the ``||brick:Brick||`` Toolbox drawer. Drag an ``||brick:on button||`` block onto the Workspace, and place it anywhere on the Workspace.
|
|
|
|
```blocks
|
|
brick.buttonEnter.onEvent(ButtonEvent.Pressed, function () {
|
|
|
|
})
|
|
```
|
|
|
|
## Step 2
|
|
|
|
Open the ``||motors:Motors||`` Toolbox drawer. Drag out a ``||motors:run||`` block onto the Workspace, and drop it into the ``||brick:on button||`` block.
|
|
|
|
```blocks
|
|
brick.buttonEnter.onEvent(ButtonEvent.Pressed, function () {
|
|
motors.largeA.run(50)
|
|
})
|
|
```
|
|
|
|
## Step 3
|
|
|
|
Open the ``||logic:Logic||`` Toolbox drawer. Drag out an ``||logic:if then||`` block onto the Workspace, and drop it into the ``||loops:forever||`` block.
|
|
|
|
```blocks
|
|
forever(function () {
|
|
if (true) {
|
|
|
|
}
|
|
})
|
|
```
|
|
|
|
## Step 4
|
|
|
|
Open the ``||sensors:Sensors||`` Toolbox drawer. Drag out a ``||sensors:touch is pressed||`` block onto the Workspace, and drop it in the ``||logic:if then||`` block replacing ``true``.
|
|
|
|
```blocks
|
|
forever(function () {
|
|
if (sensors.touch1.isPressed()) {
|
|
|
|
}
|
|
})
|
|
```
|
|
|
|
## Step 5
|
|
|
|
Open the ``||music:Music||`` Toolbox drawer. Drag out a ``||music:play sound effect||`` block onto the Workspace, and drop it under the ``||logic:if then||`` block.
|
|
|
|
```blocks
|
|
forever(function () {
|
|
if (sensors.touch1.isPressed()) {
|
|
music.playSoundEffect(sounds.animalsCatPurr)
|
|
}
|
|
})
|
|
```
|
|
|
|
## Step 6
|
|
|
|
In the ``||music:play sound effect||`` block, use the drop-down menu to select the ``information touch`` sound effect.
|
|
|
|
```blocks
|
|
forever(function () {
|
|
if (sensors.touch1.isPressed()) {
|
|
music.playSoundEffect(sounds.informationTouch)
|
|
}
|
|
})
|
|
```
|
|
|
|
## Step 7
|
|
|
|
Open the ``||motors:Motors||`` Toolbox drawer. Drag out a ``||motors:stop||`` block onto the Workspace, and drop it in after the ``||music:play sound effect||`` block.
|
|
|
|
```blocks
|
|
forever(function () {
|
|
if (sensors.touch1.isPressed()) {
|
|
music.playSoundEffect(sounds.informationTouch)
|
|
motors.largeA.stop()
|
|
}
|
|
})
|
|
```
|
|
|
|
## Step 8
|
|
|
|
Now, plug your @boardname@ into the computer with the USB cable, and click the **Download** button at the bottom of your screen. Follow the directions to save your program to the brick.
|
|
|
|
Attach a Large motor to Port A, and a Touch sensor to Port 1 on your brick. Test your program by pressing the ENTER button. When the motor starts, press the touch sensor. Does the motor stop as expected?
