/*
Twitter Client with Strings
This sketch connects to Twitter using an Ethernet shield. It parses the XML
returned, and looks for <text>this is a tweet</text>
You can use the Arduino Ethernet shield, or the Adafruit Ethernet shield,
either one will work, as long as it's got a Wiznet Ethernet module on board.
This example uses the DHCP routines in the Ethernet library which is part of the
Arduino core from version 1.0 beta 1
This example uses the String library, which is part of the Arduino core from
version 0019.

- make Firmata a subclass of HardwareSerial
- per-pin digital callback, since the per-port callback is a bit complicated
for beginners (maybe Firmata is not for beginners...)
- simplify SimpleDigitalFirmata, take out the code that checks to see if the
data has changed, since it is a bit complicated for this example. Ideally
this example would be based on a call
- turn current SimpleDigitalFirmata into DigitalPortFirmata for a more complex
example using the code which checks for changes before doing anything
- test integration with Wiring

This example connects to a WEP-encrypted Wifi network.
Then it prints the MAC address of the Wifi shield,
the IP address obtained, and other network details.
If you use 40-bit WEP, you need a key that is 10 characters long,
and the characters must be hexadecimal (0-9 or A-F).
e.g. for 40-bit, ABBADEAF01 will work, but ABBADEAF won't work
(too short) and ABBAISDEAF won't work (I and S are not
hexadecimal characters).
For 128-bit, you need a string that is 26 characters long.
D0D0DEADF00DABBADEAFBEADED will work because it's 26 characters,
all in the 0-9, A-F range.

WiFi Web Server LED Blink
A simple web server that lets you blink an LED via the web.
This sketch will print the IP address of your WiFi Shield (once connected)
to the Serial monitor. From there, you can open that address in a web browser
to turn on and off the LED on pin 9.
If the IP address of your shield is yourAddress:
http://yourAddress/H turns the LED on
http://yourAddress/L turns it off
This example is written for a network using WPA encryption. For
WEP or WPA, change the Wifi.begin() call accordingly.

* WiFi shield attached
* LED attached to pin 9

Controller Area network (CAN) API for Arduino Due
This is a beta release of the CAN API for Arduino Due. It contains the necessary classes and functions to configure, enable, disable and use of the CAN peripherals controllers embedded in the SAM3X8E core inside Arduino Due, and the two external SN65HVD234 transceivers.
This CAN API for Arduino Due is released together with a CAN sample1 sketch for the Arduino IDE 1.5.2 and it shows how to configure the CAN controllers and how to manage CAN message transfers. The two CAN controllers (CAN0 and CAN1) and two mailboxes (mailbox 0 and mailbox 1) are used: CAN0 mailbox 0 is configured as transmitter, and CAN1 mailbox 0 is configured as receiver. The communication baudrate is 1Mbit/s. The CAN0 controller tries to send on the bus messages through the mailbox 0 and waits for messages from mailbox 1 on CAN1 controller.
It is required to use the two CAN pins in Arduino Due, connected to the two external SN65HVD234transceivers in loop mode via a pair cable. The CAN message transaction can be monitored by a serial UART connection (115.2 Kbps, 8 data bits, no parity, 1 stop bit, no flux control) or serial monitor of the Arduino IDE 1.5.2 with autoscroll and newline modes activated.
Source files:
- CAN.cpp
- CAN.h
- sn65hvd234.c
- sn65hvd234.h
- variant.cpp
- variant.h
CAN files (.cpp .h) contain the CANRaw class with 38 functions.
sn65hvd234 files (.c .h) contain 7 driver functions.
The variant files (.cpp .h) are updates to the IDE 1.5.2 ones. Added initialization of the CAN pins in variant.cpp
and CAN pins definition in variant.h.
Hardware requirements:
- Arduino Due board
- Dual CAN transceiver shield
- Twisted shielded pair cable
Software requirements:
- Arduino IDE 1.5.2
- CAN API library
To perform the CAN sample 1 test, the pair cable needs to be connected between the two CAN ports as follows:
CANRX0 <-> CANRX0
CANRX1 <-> CANRX1
Once the CAN sample 1 and the CAN library are loaded in Arduino IDE 1.5.2, after serial monitor open or after a reset of the Arduino board, the following message should be displayed in the monitor terminal: Type CAN message to send. Then, an 8 digit message can be typed and after a return stroke of the keyboard, the following message should be displayed: Sent value=XXXXXXXX, where XXXXXXXX is the typed message. If the message was sent/received successfully, the following message should be displayed: CAN message received=XXXXXXX and End of test. Otherwise, there is a CAN communication error.

*
* NOTE: UDP is fast, but has some important limitations (thanks to Warren Gray for mentioning these)
* 1) UDP does not guarantee the order in which assembled UDP packets are received. This
* might not happen often in practice, but in larger network topologies, a UDP
* packet can be received out of sequence.
* 2) UDP does not guard against lost packets - so packets *can* disappear without the sender being
* aware of it. Again, this may not be a concern in practice on small local networks.

Digital Pot Control
This example controls an Analog Devices AD5206 digital potentiometer.
The AD5206 has 6 potentiometer channels. Each channel's pins are labeled
A - connect this to voltage
W - this is the pot's wiper, which changes when you set it
B - connect this to ground.
The AD5206 is SPI-compatible,and to command it, you send two bytes,
one with the channel number (0 - 5) and one with the resistance value for the
channel (0 - 255).
The circuit:
* All A pins of AD5206 connected to +5V
* All B pins of AD5206 connected to ground
* An LED and a 220-ohm resisor in series connected from each W pin to ground
* CS - to digital pin 10 (SS pin)
* SDI - to digital pin 11 (MOSI pin)
* CLK - to digital pin 13 (SCK pin)

/*
A servo is activated by creating an instance of the Servo class passing the desired pin to the attach() method.
The servos are pulsed in the background using the value most recently written using the write() method
Note that analogWrite of PWM on pins associated with the timer are disabled when the first servo is attached.
Timers are seized as needed in groups of 12 servos - 24 servos use two timers, 48 servos will use four.
The sequence used to sieze timers is defined in timers.h
The methods are:
Servo - Class for manipulating servo motors connected to Arduino pins.
attach(pin ) - Attaches a servo motor to an i/o pin.
attach(pin, min, max ) - Attaches to a pin setting min and max values in microseconds
default min is 544, max is 2400
write() - Sets the servo angle in degrees. (invalid angle that is valid as pulse in microseconds is treated as microseconds)
writeMicroseconds() - Sets the servo pulse width in microseconds
read() - Gets the last written servo pulse width as an angle between 0 and 180.
readMicroseconds() - Gets the last written servo pulse width in microseconds. (was read_us() in first release)
attached() - Returns true if there is a servo attached.
detach() - Stops an attached servos from pulsing its i/o pin.

/*
Wifi Pachube sensor client with Strings
This sketch connects an analog sensor to Pachube (http://www.pachube.com)
using a Arduino Wifi shield.
This example is written for a network using WPA encryption. For
WEP or WPA, change the Wifi.begin() call accordingly.
This example has been updated to use version 2.0 of the pachube.com API.
To make it work, create a feed with a datastream, and give it the ID
sensor1. Or change the code below to match your feed.
This example uses the String library, which is part of the Arduino core from
version 0019.
Circuit:
* Analog sensor attached to analog in 0
* Wifi shield attached to pins 10, 11, 12, 13
