****************************************************************************
*
* To connect an Arduino to the CC3000 you'll need to make these 6 connections
* (in addition to the WiFi antenna, power etc).
*
* Name / pin on CC3000 module / pin on CC3000EM board / purpose
*
* SPI_CS / 12 / J4-8 / SPI Chip Select
* The Arduino will set this pin LOW when it wants to
* exchange data with the CC3000. By convention this is
* Arduino pin 10, but any pin can be used. In this
* program it will be called WLAN_CS
*
* SPI_DOUT / 13 / J4-9 / Data from the module to the Arduino
* This is Arduino's MISO pin, and is how the CC3000
* will get bytes to the Arduino. For most Arduinos
* MISO is pin 12
*
* SPI_IRQ / 14 / J4-10 / CC3000 host notify
* The CC3000 will drive this pin LOW to let the Arduino
* know it's ready to send data. For a regular Arduino
* (Uno, Nano, Leonardo) this will have to be connected
* to pin 2 or 3 so you can use attachInterrupt(). In
* this program it will be called WLAN_IRQ
*
* SPI_DIN / 15 / J4-11 Data from the Arduino to the CC3000
* This is the Arduino's MOSI pin, and is how the Arduino
* will get bytes to the CC3000. For most Arduinos
* MOSI is pin 11
*
* SPI_CLK / 17 / J4-12 SPI clock
* This is the Arduino's SCK pin. For most Arduinos
* SCK is pin 13
*
* VBAT_SW_EN / 26 / J5-5 Module enable
* The Arduino will set this pin HIGH to turn the CC3000
* on. Any pin can be used. In this program it will be
* called WLAN_EN
*
* WARNING #1: The CC3000 runs at 3.6V maximum so you can't run it from your
* regular 5V Arduino power pin. Run it from 3.3V!
*
* WARNING #2: When transmitting the CC3000 will use up to 275mA current. Most
* Arduinos' 3.3V pins can only supply up to 50mA current, so you'll need a
* separate power supply for it (or a voltage regulator like the LD1117V33
* connected to your Arduino's 5V power pin).
*
* WARNING #3: The CC3000's IO pins are not 5V tolerant. If you're using a 5V
* Arduino you will need a level shifter to convert these signals to 3.3V
* so you don't blow up the module.
*
* You'll need to shift the pins for WLAN_CS, MOSI, SCK, and WLAN_EN. MISO can be
* connected directly because it's an input pin for the Arduino and the Arduino
* can read 3.3V signals directly. For WLAN_IRQ use a pullup resistor of 20K to
* 100K Ohm -- one leg to the Arduino input pin + CC3000 SPI_IRQ pin, the other
* leg to +3.3V.
*
* You can use a level shifter chip like the 74LVC245 or TXB0104 or you can use
* a pair of resistors to make a voltage divider like this:
*
* Arduino pin -----> 560 Ohm --+--> 1K Ohm -----> GND
* |
* |
* +---> CC3000 pin
