Description
Physical Computing is all around us. Our smartphones, our cars, our washing machines, all are examples of physical computing. Even our toaster has become smart these days. Smart meaning controlled by a micro-controller, and physical computing meaning some electronic components controlled by a micro-controller. If these electronic components are electric motors, magnets or other actuators, then the electronic becomes physical, meaning something moves. But physical also means measuring things like temperature, sound, and light. We want to learn about all these, about electronics, about electronic components, and about micro-controllers.

We start with a little bit of history, not because usually that's what one does, but because many of the concepts and components become really easy to grasp and understand. After having seen some of the origins, we then learn about simple electric circuits and simple electronic components. We get to know batteries, switches, resistors, capacitors and inductors. And we will briefly hear about Ohms law and Kirchhoff's circuit laws. We also get to learn how to use the circuit simulator. Then the active electronic components follow, such as diodes, LEDs, and transistors. We learn about the different type of diodes that there are and what they are used for. We get to know transistors, bipolar and field-effect, and how to use them as switches and as amplifiers. We get to see the multivibrators, especially the astable and the bistable, and learn why they are so important for computers. After these introductory chapters, we have enough of a foundation to do some real physical computing. We will use an Arduino and connect it with the different electronic components we learned about in the previous chapters.
