Make: Robotic Arms

11Chapter 1: The Foundation of Robotic Arms

WHAT ARE WE BUILDING?

In our first project, we’re going to begin by learning about

some basic building blocks we’ll use to build circuits

throughout this book. Then we’ll construct our first servo

circuit. In project 1, our goal is to understand the circuity and

code needed to control the angle of a servo.

Before we build our first circuit, we need to talk about a useful tool for

building electronics prototypes: the humble breadboard (Figure

1-13

)

—a small plastic base with lots of holes for plugging in wires and

components to connect them. Breadboards come in all shapes and

sizes, but most operate in ...
