Basic robot control

In this recipe, we are finally going to dive into the core of this chapter: making our robot move around! We'll learn how to configure it so it can receive commands via Wi-Fi, and then we'll learn how to control it using a simple interface running inside your browser.

char password[] = "wifi-pass';

After that, we declare...
