Summary

In this chapter, we had a look at yet more ways to interface with hardware over the GPIO port that includes using pulse width modulation, which can be used to drive devices such as the servos used in this chapter. We also took a look at how to emulate an analog signal, which can then be used, for example, to control the brightness of an LED.

We also took a look at the ways in which the Raspberry Pi camera can be accessed remotely using the V4 L streaming server. In the server, the same control and streaming options that are available to the local applications are made available to the devices on the same network.

In the next chapter, we will look at how to use the Pi for a true ubiquitous computing project, which will combine an information display into a fairly standard mirror.
