Summary
Now that we've completed the fifth chapter, let's review some of the main tasks you learned how to do:
- Driving LEDs and sensing switches using digital I/O ports and unearthing the potential problems and restrictions that apply to their use
- Adding a switch interface with an activity indicator LED to the Internet radio project from Chapter 4, Raspberry Pi Audio Input and Output
In the next chapter, you will start to exercise some of the Raspberry Pi input and output ports to drive RC-servos over the I2C (SMBUS) interface.
