# Blink to Light
## Introduction @unplugged
Blink an LED where the tempo is controlled by a light sensor.
## Step 1 @fullscreen
Add the code to drives a **blinking LED** on pin **D0**.
```blocks
forever(function () {
pins.D0.digitalWrite(true)
pause(100)
pins.D0.digitalWrite(false)
pause(100)
})
```
## Step 2 @fullscreen
Insert a ``||pins:analog read||`` block for **A0** in the first ``||loops:pause||`` block.
The ``||pins:analog read||`` returns a value between 0 (no input) to 1023 (full input) which will be translated in milliseconds of pause.
```blocks
forever(function () {
pins.D0.digitalWrite(true)
pause(pins.A0.analogRead())
pins.D0.digitalWrite(false)
pause(100)
})
```
## Step 3 @fullscreen
Look at the simulator and make sure your program works as expected.
If you have a @boardname@, press ``|Download|`` and follow the instruction to get your code on your device.
Click on the **wrench** icon under the simulator to get detailed breadboarding instructions.
```config
feature=uf2
feature=pind0
feature=pina0
