# Touch to Run
|
||
|
||
## Introduction @fullscreen
|
||
|
||
Use the Touch sensor to run a motor.
|
||
|
||
|
||
|
||
## Step 1
|
||
|
||
Open the ``||sensors:Sensors||`` Toolbox drawer. Drag out **2** ``||sensors:on touch||`` blocks onto the Workspace (you can place these anywhere).
|
||
|
||
```blocks
|
||
sensors.touch1.onEvent(ButtonEvent.Pressed, function () {
|
||
|
||
})
|
||
sensors.touch1.onEvent(ButtonEvent.Pressed, function () {
|
||
|
||
})
|
||
```
|
||
|
||
## Step 2
|
||
|
||
In one of the ``||sensors:on touch||`` blocks, use the second drop-down menu to change from ``pressed`` to ``released``.
|
||
|
||
|
||
|
||
```blocks
|
||
sensors.touch1.onEvent(ButtonEvent.Pressed, function () {
|
||
|
||
})
|
||
sensors.touch1.onEvent(ButtonEvent.Released, function () {
|
||
|
||
})
|
||
```
|
||
|
||
## Step 3
|
||
|
||
Open the ``||motors:Motors||`` Toolbox drawer. Drag out a ``||motors:run||`` block onto the Workspace, and drop it into the ``||brick:on touch pressed||`` block.
|
||
|
||
```blocks
|
||
sensors.touch1.onEvent(ButtonEvent.Pressed, function () {
|
||
motors.largeA.run(50)
|
||
})
|
||
sensors.touch1.onEvent(ButtonEvent.Released, function () {
|
||
|
||
})
|
||
```
|
||
|
||
## Step 4
|
||
|
||
Open the ``||motors:Motors||`` Toolbox drawer. Drag out a ``||motors:stop||`` block onto the Workspace, and drop it into the ``||sensors:on touch released||`` block.
|
||
|
||
```blocks
|
||
sensors.touch1.onEvent(ButtonEvent.Pressed, function () {
|
||
motors.largeA.run(50)
|
||
})
|
||
sensors.touch1.onEvent(ButtonEvent.Released, function () {
|
||
motors.largeA.stop()
|
||
})
|
||
```
|
||
|
||
## Step 5
|
||
|
||
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 and releasing the touch sensor – does the motor start and stop as expected?
