== Fundamentals, Part IV: Flow Control ==

Flow control is a term used generally for programming languages for determining in what order code is executed. This principle also applies to integrated circuits. The proper management of how a pulse goes to each component in the correct order is very important for large or complex machines.

Fortunately, there are some components to help with organizing your flow control. For example, there are pulse splitters to allow for cleaner wiring by transforming a single input into multiple outputs. Delay timers also exist so that you can make sure everything goes off at the right time (although it's best if your machine is not dependent on that, which is known as a race condition in programming.) Many circuits will also propagate a pulse if it passes a certain condition, like logic gates, ensuring that something will occur only if you want it to.

Here's a somewhat terrifying chart illustrating the concept:

When the button is pressed, the first thing to happen is for the global positioning system to gather its coordinates. Immediately after this, the X screen loads its data, and then the Y screen. These screens have the X-coordinate and Y-coordinate from the GPS respectively as their displayed data. Because the GPS gathers coordinates before the screens load their data, it displays the coordinates without a hitch, but if the screens were to load first, then it would not display the coordinates correctly, instead displaying the coordinates ''last'' recorded - so if you pressed it at one spot and then moved a few rooms away and pressed it again, the coordinates displayed would be for the first spot, even though the GPS's recorded data is in the new room, because the screens updated before the coordinates did!
