So you have read part one and curious to find out what there is out there to use.
I am going to try and keep this as current as possible with some history thrown in
I will publish a list of types and specifications and possible uses for each one.
Once we have this I will select a few for some new posts with projects to 3D print and code.
This is where it gets all a bit technical – so buckle up and get ready for an information overload.
Along with all the arduino’s there are a raft of shields (extra board for specific jobs that attach and enhance the arduinos)
So firstly we need to categorise them as follows

Arduino 101 & Genuino 101 combine the ease-of-use of the classic boards with the latest technologies. The board recognises gestures, and features a six-axis accelerometer and gyroscope. Control your projects with your phone over Bluetooth connectivit
Arduino Pro

Analog Input Pins 6
DC Current per I/O Pin 40 mA
Flash Memory 16 KB (ATmega168) or 32KB (ATmega328) of which 2 KB used by bootloader
SRAM 1 KB (ATmega168) or 2 KB (ATmega328)
EEPROM 512 bytes (ATmega168) or 1 KB (ATmega328)
Clock Speed 8 MHz (3.3V versions) or 16 MHz (5V versions)
Possible Projects
The Arduino Pro is intended for semi-permanent installation in objects or exhibitions. The board comes without pre-mounted headers, allowing the use of various types of connectors or direct soldering of wires. The pin layout is compatible with Arduino shields. The 3.3V versions of the Pro can be powered with a battery.
Arduino Pro Mini

Analog Input Pins 6
DC Current per I/O Pin 40 mA
Flash Memory 32 kB (of which 0.5 kB used by bootloader)
SRAM 2 kB
EEPROM 1 kB
Clock Speed 8 MHz (3.3V model) or 16 MHz (5V model)
Possible Projects
The Arduino Pro Mini is intended for semi-permanent installation in objects or exhibitions. The board comes without pre-mounted headers, allowing the use of various types of connectors or direct soldering of wires. The pin layout is compatible with the Arduino Mini.
There are two version of the Pro Mini. One runs at 3.3V and 8 MHz, the other at 5V and 16 MHz.
Arduino Micro
Microcontroller ATmega32U4
Operating Voltage 5V
Input Voltage (recommended) 7-12V
Input Voltage (limit) 6-20V
Digital I/O Pins 20
PWM Channels 7
Analog Input Channels 12

DC Current for 3.3V Pin 50 mA
Flash Memory 32 KB (ATmega32U4) of which 4 KB used by bootloader
SRAM 2.5 KB (ATmega32U4)
EEPROM 1 KB (ATmega32U4)
Clock Speed 16 MHz

Width 18 mm
Weight 13 g
Possible Projects
The Micro is the smallest board of the family, easy to integrate it in everyday objects to make them interactive. The Micro is based on the ATmega32U4 microcontroller featuring a built-in USB which makes the Micro recognisable as a mouse or keyboard

Possible projects
The one I have made is a 3d scanner which will be the subject of another blog.
Arduino Motor Shield
The Arduino Motor Shield is based on the L298 (datasheet), which is a dual full-bridge driver designed to drive inductive loads such as relays, solenoids, DC and stepping motors. It lets you drive two DC motors with your Arduino board, controlling the speed and direction of each one independently. You can also measure the motor current absorption of each motor, among other features. The shield is TinkerKit compatible, which means you can quickly create projects by plugging TinkerKit modules to the board.
Operating Voltage 5V to 12V
Motor controller L298P, Drives 2 DC motors or 1 stepper motor
Max current 2A per channel or 4A max (with external power supply)
Current sensing 1.65V/A
Free running stop and brake function
Possible projects
Anything that you would like with motors , robots,cnc machines etc.
