# Switchy
## Introduction @unplugged
Attach a switch on a digital pin to turn a LED on or off.
```template
forever(function () {
})
```
## Step 1 @fullscreen
Add ``||pins:digital write||`` under the ``||loops:forever||`` to set pin **D1** to ``LOW`` (false).
```blocks
forever(function () {
pins.D1.digitalWrite(false)
})
```
## Step 2 @fullscreen
Add ``||pins:digital read||`` in the ``LOW``/``HIGH`` slot. Change the pin to **D0**.
```blocks
forever(function () {
pins.D1.digitalWrite(pins.D0.digitalRead())
})
```
## Step 3 @fullscreen
Look at the simulator and test if your program works as you would expect. If you move the switch, the LED
should turn on and off.
## Step 4 @fullscreen
Click ``||Download||`` to download your code into your board and click the **wrench** to get detailled
breadboarding instructions.
