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).

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.

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.

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.

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?
