**Video.** The CPX working as a USB mouse, which we'll build in this lesson—first nudging the cursor with the A and B buttons, then steering it continuously by tilting the board.

In Lesson 7 of our CPX series, we will learn how to use the CPX as a programmable mouse. We'll begin by making a discrete mouse that shifts the mouse cursor by small amounts with button A and B presses before building a more complex accelerometer-based mouse with continuous input.
In this lesson, we will show how to use the CPX as a programmable mouse.
In this lesson, we will show how to use the CPX's built-in accelerometer to make smooth, continuous mouse input.

In the next lesson, we'll learn how to hook up external sensors like potentiometers using analog input on the CPX.
