Blink to Light

Introduction

Blink an LED where the tempo is controlled by a light sensor.

Step 1

Add the code to drives a blinking LED on pin D0.

forever(function () {
    pins.D0.digitalWrite(true)
    pause(100)
    pins.D0.digitalWrite(false)
    pause(100)
})

Step 2

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.

forever(function () {
    pins.D0.digitalWrite(true)
    pause(pins.A0.analogRead())
    pins.D0.digitalWrite(false)
    pause(100)
})

Step 3

Look at the simulator and make sure your program works as expected.
