Arduino Sketches: Tools and Techniques for Programming Wizardry

CHAPTER23

Bridge

This chapter discusses the following functions of the Bridge library:

• Bridge.begin()
• Bridge.put()
• Bridge.get()
• Process.begin()
• Process.addParameter()
• Process.run()
• Process.runAsynchronously()
• Process.running()
• Process.exitValue()
• Process.read()
• Process.write()
• Process.flush()
• Process.close()
• FileSystem.begin()
• FileSystem.open()
• FileSystem.exists()
• FileSystem.rmdir()
• FileSystem.remove()
• YunServer.begin()
• YunClient.connected()
• YunClient.stop()

The hardware needed to use these functions includes:

• Arduino Yún
• 1 × Breadboard
• 1 × LDR
• 1 × 10 kΩ resistor
• Wires

Introducing Bridge Library

There is often confusion as to the name of a microcontroller. A microcontroller (as the name implies) controls, whereas a microprocessor processes data. This becomes apparent for the Arduino Yún, where both are present.

In December 2002, Linksys released its WRT54G residential wireless router. It was a small device with two antennae behind a blue-and-black cover. Behind were four Ethernet LAN ports and an uplink port. It was an easy way to add high-speed Wi-Fi to a home network and was used by a large number of people, including myself. My WRT54G increased my wireless range at home and allowed me higher speeds than what my Internet modem provided. (The WRT54G provided Wi-Fi-G instead of the aging ...
