with Python

At the end of Chapter 6, you did a little bit

of programming with the Raspberry Pi’s

GPIO pins using a shell script. In this chap-

ter, you’re going to learn how to use Python

to do the same thing… and a little more.

As with the shell script, Python will let you

access the GPIO pins with code that reads

and controls the pins automatically.

The advantage that Python has over shell scripting is that Python

code is easier to write and is more readable. There’s also a whole

slew of Python modules that make it easy for you to do some

complex stuff with basic code. See Table 4-2 for a list of a few

modules that might be useful in your projects. Best of all, there’s
