The Basics Statements are grouped together by curly brackets { }, not by indentation (as in Python). You can put newlines and spaces where you like, but your code will be easier to read if you indent it (like Python)....

In previous lessons the code calculated the time for a revolution, so as a final exercise, let's display! Actually, rotational speed is more often measured in revolutions per minute (RPM), but we can easily calculate that. We calculated the time...

You can display messages just as well as patterns since each letter, digit or symbol is just a pattern. Luckily for us, someone has already worked out all the patterns we need and a function for displaying them! Save your...

You will have noticed that the patterns you've made so far spin round, because we haven't told the Lightino when to start during a rotation. This is what the sensor is for. We write to the LEDs with a digitalWrite() function, so...

In the last lesson we used code to decide which LEDs to turn on or off to make a pattern. But what if we want to make it show a pattern such as a heart? If we draw the pattern...

How to drive the LEDs We're now ready to start the fun! But first we need to understand how the LEDs work. Each of the 8 LEDs is actually 3 LEDs in one package: a red, a green and a...
