# Touch to Run ## Introduction @unplugged Use the Touch Sensor to run a motor. ![Large motor connected to brick](/static/tutorials/touch-to-run/touch-to-run.gif) ## Step 1 Open the ``||sensors:Sensors||`` Toolbox drawer. Drag out **2** ``||sensors:on touch||`` blocks anywhere onto the Workspace. ```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``. ![Touch sensor action dropdown](/static/tutorials/touch-to-run/on-touch-dropdown.png) ```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 ``||sensors: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 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 EV3 Brick. Attach a Large Motor to Port A, and a Touch Sensor to Port 1 on your EV3 Brick. Test your program by pressing and releasing the touch sensor – does the motor start and stop as expected?
