A very quick and dirty introduction to
Sensors, Microcontrollers, and Electronics

Part Three: how sensors and actuators work and how to hook them up to a microcontroller

There are gazillions of different kinds of sensors and actuators. You probably use at least a hundred of them a day. Luckily for us they mostly fall into a few broad categories, as we saw in part one. It generally not necessary to know the intimate details of how a sensor/actuator works in order to use it. Most of the time it's sufficient to simply understand how to get information and electricity into and out of the device.



What's next?

You have to actually do something now!
