Arduino Uno Rev 3 (by Make:) is a product we worked closely with the good folks at Arduino to bring you. Functionally, they are identical to a regular Arduino Uno R3 (with SMD microcontroller) but feature exclusive Make branding to set them apart from the rest! The front showcases the Make logo in a partially gridded white racing stripe. The back features a blue Make Robot which contrasts nicely against a white background. These Arduinos look so good you may want to get two - one for your project and one for display!

 

Arduino is an amazing tool for physical computing — it's an open source microcontroller board, plus a free software development environment. Use it to make cool interactive objects that can sense inputs from switches, sensors, and computers — and then control motors, lights, and other physical outputs in the real world. This special Make branded version features an SMD chip hard soldered to board.

 

The Uno is compatible with all current shields and code, and comes assembled — simply connect it to a computer with a USB cable or power it with a AC-to-DC adapter or battery.

Power
The Arduino Uno can be powered via the USB connection or with an external power supply. External (non-USB) power can come either from an AC-to-DC adapter (wall-wart) or battery. Leads from a battery can be inserted in the Gnd and Vin pin headers of the POWER connector. The recommended range is 7 to 12 volts.

    The Power Pins are as fallows
  • VIN. The input voltage to the Arduino board when it's using an external power source (as opposed to 5 volts from the USB connection or other regulated power source). You can supply voltage through this pin, or, if supplying voltage via the power jack, access it through this pin.
  • 5V.This pin outputs a regulated 5V from the regulator on the board. The board can be supplied with power either from the DC power jack (7 - 12V), the USB connector (5V), or the VIN pin of the board (7-12V). Supplying voltage via the 5V or 3.3V pins bypasses the regulator, and can damage your board. We don't advise it.
  • 3V3. A 3.3 volt supply generated by the on-board regulator. Maximum current draw is 50 mA.
  • GND. Ground pins.
  • IOREF. This pin on the Arduino board provides the voltage reference with which the microcontroller operates. A properly configured shield can read the IOREF pin voltage and select the appropriate power source or enable voltage translators on the outputs for working with the 5V or 3.3V.


Input and Output
Each of the 14 digital pins on the Uno can be used as an input or output, using pinMode(), digitalWrite(), and digitalRead() functions. They operate at 5 volts. Each pin can provide or receive a maximum of 40 mA and has an internal pull-up resistor (disconnected by default) of 20-50 kOhms. In addition, some pins have specialized functions:
  • Serial: 0 (RX) and 1 (TX). Used to receive (RX) and transmit (TX) TTL serial data. These pins are connected to the corresponding pins of the ATmega8U2 USB-to-TTL Serial chip.
  • External Interrupts: 2 and 3. These pins can be configured to trigger an interrupt on a low value, a rising or falling edge, or a change in value. See the attachInterrupt() function for details.
  • PWM: 3, 5, 6, 9, 10, and 11. Provide 8-bit PWM output with the analogWrite() function.
  • SPI: 10 (SS), 11 (MOSI), 12 (MISO), 13 (SCK). These pins support SPI communication using the SPI library.
  • LED: 13. There is a built-in LED connected to digital pin 13. When the pin is HIGH value, the LED is on, when the pin is LOW, it's off.
The Uno has 6 analog inputs, labeled A0 through A5, each of which provide 10 bits of resolution (i.e. 1024 different values). By default they measure from ground to 5 volts, though is it possible to change the upper end of their range using the AREF pin and the analogReference() function. Additionally, some pins have specialized functionality:
  • TWI: A4 or SDA pin and A5 or SCL pin. Support TWI communication using the Wire library.
  • There are a couple of other pins on the board:
  • AREF. Reference voltage for the analog inputs. Used with analogReference().
  • Reset. Bring this line LOW to reset the microcontroller. Typically used to add a reset button to shields, which block the one on the board.
