The Fox Song has been released on 3rd September 2013 on YouTube! Now I am giving it away to you for FREE ON LITTLEBIGPLANET!!! (Copyright, this song has come from the official YouTube music video. All rights reserved.)
Here is a video of the song if you don't know what the song is:
We can now perform 3 basic mathematical functions; Addition, Subtraction and Multiplication. So you may be asking yourself now "How can I divide?". Before we look at how division works we're going to learn about using a speed scale timer to create equilibrium in a system. In a formal mathematical sense we can use this to perform the inverse of an operation. So given that we are already able to multiply we can apply this knowledge to perform the inverse of multiplication; division.
We can perform 'static multiplication' in LBP through addition by adding a signal to itself a number of times; for example, with a signal of 5%;
5 x 3 = 5 + 5 + 5 = 15%
I say 'static multiplication' because through this method we can only multiply our signal by the same amount (in this case 3) for every signal we plug in but what if we want to multiply one signal by another signal where both signals can be changing? For this we need to look at speed
At the end of the last tutorial we made note of how we could detect an analog signal. We said that we could use a positional sequencer with a battery that fills the entire sequencer (see figure 1). This ensures that if any signal is plugged into the sequencer, the battery will become active and give out a 100% ON output signal.
The Problem with Sequencers -
This is good but there is a problem with it. Sequencers are
We can use analog signals within LBP2 to perform some useful mathematical functions such as multiplication, division, addition, subtraction. We can also perform comparisons of signals to determine whether one signal is larger than another, whether they are equal etc. We will learn how to perform all of these functions eventually but as with all things we will begin with the basics.
Addition / Subtraction
In LBP2 the direction combiner allows us to subtract one signal from another
