Frequency Clock Speed. Arduino Uno is a microcontroller board based on 8-bit ATmegaP microcontroller.

Along with ATmegaP, it consists other components such as crystal oscillator, serial communication, voltage regulator, etc. Each pin operate at 5V and can provide or receive a maximum of 40mA current, and has an internal pull-up resistor of KOhms which are disconnected by default. Out of these 14 pins, some pins have specific functions as listed below:.

Along with 14 Digital pins, there are 6 analog input pins, each of which provide 10 bits of resolution, i. They measure from 0 to 5 volts but this limit can be increased by using AREF pin with analog Reference function.

Arduino can be used to communicate with a computer, another Arduino board or other microcontrollers. An ATmega16U2 on the board channels this serial communication over USB and appears as a virtual com port to software on the computer.

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 Provide 8-bit PWM output with the analogWrite function. LED: There is a built-in LED connected to digital pin There are 6 analog inputs, labeled A0 through A5, each of which provide 10 bits of resolution i. 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.

The Uno has 6 analog inputs, labeled A0 through A5, each of which provide 10 bits of resolution i. 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. There are a couple of other pins on the board: AREF. Reference voltage for the analog inputs.

Used with analogReference. Bring this line LOW to reset the microcontroller.

Typically used to add a reset button to shields which block the one on the board. An ATmega16U2 on the board channels this serial communication over USB and appears as a virtual com port to software on the computer. The Arduino Software IDE includes a serial monitor which allows simple textual data to be sent to and from the board.

When this line is asserted taken low , the reset line drops long enough to reset the chip.In future posts, we will take you step by step in creating your first simple Arduino project. Each of the 14 digital pins can be used as an input or output, using pinMode , digitalWrite , and digitalRead functions.
