The Arduino Distinto is a microcontroller board based on the ATmega328 (datasheet). It has 14 digital input/output buy-ins (of which will 6 can be used as PWM outputs), six analog advices, a of sixteen MHz hard resonator, a USB connection, a power jack, an ICSP header, and a reset button. It includes everything needed to support the microcontroller; merely connect that to a computer system with a UNIVERSAL SERIAL BUS cable or perhaps power this with a AC-to-DC adapter or battery to get going. The Distinto differs via all earlier boards for the reason that it does not make use of the FTDI USB-to-serial driver nick. Instead, it features the Atmega16U2 (Atmega8U2 up to variation R2) developed as a USB-to-serial converter. Revising 2 of the Uno board has a resistor pulling the 8U2 HWB line to ground, making it easier to put into DFU function. Revision a few of the table has the next new features:
* 1 . zero pinout: added SDA and SCL limits that are near the AREF pin number and two other new pins put near to the RESET pin, the IOREF that allow the glasses to adjust to the ac electricity provided from your board. At a later date, shields will be compatible both equally with the plank that use the AVR, which usually operate with 5V current Arduino Due that operate with 3. 3V. The second one is a not connected pin, that may be reserved for upcoming purposes. 2. Stronger RESET circuit.
* Atmega 16U2 replace the 8U2.
" Uno" means one in Italian language and is named to indicate the forthcoming release of Arduino 1 . 0. The Uno and version 1 ) 0 is definitely the reference variations of Arduino, moving forward. The Uno is a latest within a series of USB Arduino boards, and the reference model intended for the Arduino platform; for any comparison with previous versions, see the index of Arduino boards.

Schematic & Reference Design
EAGLE files: arduino-uno-Rev3-reference-design. zip (NOTE: works with Eagle 6. zero and newer) Schematic: arduino-uno-Rev3-schematic. pdf
Note: The Arduino reference design are able to use an Atmega8, 168, or perhaps 328, Current models use an ATmega328, but an Atmega8 is shown in the schematic pertaining to reference. The pin construction is similar on all processors. Power
The Arduino Uno could be powered via the USB connection or perhaps with an external power supply. The strength source is selected immediately. External (non-USB) power can come either coming from an AC-to-DC adapter (wall-wart) or battery. The adapter can be connected by plugging a 2 . 1mm center-positive plug in to the board's electricity jack. Potential clients from a battery may be inserted inside the Gnd and Vin pin headers in the POWER connector. The panel can operate on an external availability of 6 to twenty volts. If perhaps supplied with less than 7V, however , the 5V pin may well supply lower than five v and the table may be unstable. If using more than 12V, the voltage limiter may get hot and destruction the plank. The advised range is usually 7 to 12 v. The power hooks are as follows:
* VIN. The insight voltage towards the Arduino plank when it's using an external electric power source (as opposed to five volts from your USB connection or perhaps other governed power source). You can source voltage through this flag, or, in the event supplying voltage via the power jack, can get on through this pin. * 5V. This pin outputs a regulated 5V through the regulator within the board. The board can be supplied with electrical power either through the DC electrical power jack (7 - 12V), the UNIVERSAL SERIAL BUS connector (5V), or the VIN pin from the board (7-12V). Supplying ac electricity via the 5V or a few. 3V hooks bypasses the...
