In "1 - Systems and Control", you saw how systems are made up from smaller subsystems. In the middle of the screen is an example control system that can be built using a FastTrack multi-purpose pcb. The "Safety Night Light" shown, uses a light sensor "input", transistor electronic switch "process" and LED "output". Move the white pointer to change the light level and see how the system has been setup to switch the LED on when it gets dark. To the left of the project is a list of the many other subsystems you can use when creating your own FastTrack pcb projects. Scroll down and see if you can see the subsystems selected for this project. If you work through the next three sections, on the far left: "2-Process", "3-Input" & "4-Output", you will see how each of these subsystem circuits work and how to set them up. The Process transistor circuit is shown first, as this is at the heart of the system. For further help getting started with FastTrack systems and its pcb, see shortcut to FastTrack "Project 0".
