USB Programming
This chapter looks at various aspects of using the Arduino with USB. This includes the keyboard and mouse emulation features provided by the Arduino Leonardo and also the reverse process of allowing a USB keyboard or mouse to be connected to a suitably equipped Arduino.
Keyboard and Mouse Emulation
Three Arduino boards—the Due, the Leonardo, and the Micro, which is based on the Leonardo—can use their USB port to emulate a keyboard or mouse. There are also Arduino-compatible boards like the LeoStick from Freetronics (Figure 13-1) that can perform this trick.
