PROJECT NAME: Arduino Uno PROJECT DESCRIPTION: The Arduino Uno is a microcontroller board based on the ATmega328 (datasheet). It has 14 digital inputoutput pins (of which 6 can be used as PWM outputs), 6 analog inputs, a 16 MHz ceramic resonator, a USB connection, a power jack, an ICSP header, and a reset button. It contains everything needed to support the microcontroller; simply connect it to a computer with a USB cable or power it with a AC-to-DC adapter or battery to get started. The Uno differs from all preceding boards in that it does not use the FTDI USB-to-serial driver chip. Instead, it features the Atmega16U2 (Atmega8U2 up to version R2) programmed as a USB-to-serial converter. Revision 2 of the Uno board has a resistor pulling the 8U2 HWB line to ground, making it easier to put into DFU mode. Revision 3 of the board has the following new features: · 1.0 pinout: added SDA and SCL pins that are near to the AREF pin and two other new pins placed near to the RESET pin, the IOREF that allow the shields to adapt to the voltage provided from the board. In future, shields will be compatible with both the board that uses the AVR, which operates with 5V and with the Arduino Due that operates with 3.3V. The second one is a not connected pin, that is reserved for future purposes. · Stronger RESET circuit. · Atmega 16U2 replace the 8U2. "Uno" means one in Italian and is named to mark the upcoming release of Arduino 1.0. The Uno and version 1.0 will be the reference versions of Arduino, moving forward. The Uno is the latest in a series of USB Arduino boards, and the reference model for the Arduino platform. This is the new Arduino Uno R3. In addition to all the features of the previous board, the Uno now uses an ATmega16U2 instead of the 8U2 found on the Uno (or the FTDI found on previous generations). This allows for faster transfer rates and more memory.

The Arduino Uno R3 is a open source microcontroller board based on the ATmega328 chip. This Board has 14 digital inputoutput pins, 6 analog input pins, Onboard 16 MHz ceramic resonator, Port for USB connection, Onboard DC power jack, An ICSP header and a microcontroller reset button. It contains everything needed to support the microcontroller. Using the board is also very easy, simply connect it to a computer with a USB cable or power it with DC adapter or battery to get started.The Uno differs from all preceding boards in that it does not use the FTDI USB-to-serial driver chip. Instead, it features the Atmega16U2Atmega8U2 up to version R2) programmed as a USB-to-serial converter. While the Arduino UNO can be powered via the USB connection or with an external power supply, the power source is selected automatically.External (non-USB) power can come either from an AC-to-DC adapter (wall-wart) or battery. The adapter can be connected by plugging a 2.1mm center-positive plug into the board's power jack. Also leads from a battery can be inserted in the Gnd and Vin pin headers of the Power connector. The board can operate on an external supply of 6 to 20 volts. If supplied with less than 7V, however, the 5V pin may supply less than five volts and the board may be unstable. If using more than 12V, the voltage regulator may overheat and damage the board. The recommended range is 5v to 12v for Arduino Uno.

Micro components are products manufactured by laser andor mechanical machining operations. The machining alters the initial shape of the fused silica or quartz starting material to yield the desired finished product geometry. These micro components are capillary and fiber-based. Fiber-based micro components are manufactured from Polymicro Technologies optical fiber. Polymicro Technologies components are an ideal solution when a simple, flat, fiber end face is not feasible. With the latest technological advances in laser micro-machining, it is now possible to incorporate special optical coupling features onto the end of an optical fiber, alleviating critical design issues. This technology greatly improves in and out light flow by having interface features micro-machined into the fiber material. Production capabilities include integral sculpted tips including side-fire designs, as well as polishing, shaping, and finishing of fiber tips. These are especially important in high-power laser applications. Capillary micro components are fused silica or quartz tubing, which has been reshaped to modify the end face geometry andor the axial diameter. Ferrules and sleeves used in optical fiber applications are typically 2.00mm or less in outer diameter; the choice of material is often based on the application wavelength. Insertion flares are common and can be machined into single (one) or dual flared (both) ends as needed. For applications such as DWDM, shaped internal geometries have been manufactured.
