In my last tutorial, I showed you how to build the pan-tilt servo assembly. So, if you haven't already built yours, I recommend checking that out first. This tutorial will show you how to program pan-tilt servos using buttons and potentiometers. The goal is to have (wired) manual control in all directions (pan: left/right and tilt: up/down). The first thing we'll do is create our circuit. There are three options to control the pan-tilt movement: potentiometers, buttons, or a joystick. The programming methodology will be similar to all of these examples.

Which controller is right for me?
When deciding on which circuit to build, I recommend thinking about how the user will use this system. Would it be easier for the user to push a button, rotate a dial, or jog a joystick? Without further delay, let's get started!
