AT THIS STAGE, YOU HAVE A SWEET-LOOKING RASPBERRY PI ROBOT THAT DOESN’T DO ANYTHING. . . YET! TO UNLOCK THE CAPABILITIES OF ALL THE HARDWARE YOU JUST WIRED UP, YOU’LL HAVE TO SINK YOUR TEETH INTO SOME MORE PROGRAMMING.
In this chapter, I’ll show you how to use the Python programming language to make your robot move. We’ll cover basic movement, making your robot remote-controlled, and varying its motor speed.

UNDERSTANDING THE H-BRIDGE
Most single-motor controllers are based around an electronics concept ...
