Microcontrollers are particularly good at ''controlling things''; hence the name. They have a set of "pins" (little spider leg type things sticking off the chip) that are called ''GPIO'' (General Purpose Input and Output) pins, or I/O pins. They can be hooked to sensors or buttons to listen to the world, or they can be hooked to lights and motors to act upon the world. These microcontroller's pins have been directly connected to the headers on the sides of the Core so you can easily access them; specifically, the pins labeled D0 to D7 and A0 to A7 are hooked directly to the microcontroller's GPIO pins. | Microcontrollers are particularly good at ''controlling things''; hence the name.
