# Using Touch Sensor Values ## Introduction @unplugged Use the Touch Sensor value to stop a running motor. ![Touch sensor and motor attached to brick](/static/tutorials/touch-sensor-values/touch-to-stop.gif) ## Step 1 Open the ``||brick:Brick||`` Toolbox drawer. Drag an ``||brick:on button||`` block onto the Workspace, and place it anywhere. ```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 EV3 Brick 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?
