Arduino uno r3 pinout

It has 14 digital input/output 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.

What is R3 in Arduino Uno?

The Arduino Uno R3 is a microcontroller board based on a removable, dual-inline-package (DIP) ATmega328 AVR microcontroller. It has 20 digital input/output pins (of which 6 can be used as PWM outputs and 6 can be used as analog inputs). Programs can be loaded on to it from the easy-to-use Arduino computer program.

What are the 14 digital pins in Arduino?

Digital Pins: The pins 4, 6, 8, 9, 10, and 12 are used as a digital input or output for the Arduino board. External Interrupt Pins: This pin of the Arduino board is used to produce the External interrupt and it is done by pin number 0, 1, 2, and 3.

What are the 3 main pin sections on the Arduino board?

Overview of the Arduino UNO Components

Analog Reference pin (orange)
Digital Ground (light green)
Digital Pins 2-13 (green)
Digital Pins 0-1/Serial In/Out - TX/RX (dark green) - These pins cannot be used for digital i/o (digitalRead and digitalWrite) if you are also using serial communication (e.g. Serial.

What is Uno R3 used for?

The Arduino Uno R3 is an open source hardware computing platform. It uses the ATmega328 microcontroller. The board also incorporates the ATmega16u2 to act as a onboard USB to serial converter. The Arduino Uno R3 can be used to develop applications that operate in a standalone or connected enviroment.

Does Arduino Uno R3 have WiFi?

WiFi	802.11 b/g/n 2.4 GHz
Wake up time	< 2 ms

Is Arduino Uno R3 and Arduino Uno same?

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.

Can Arduino run on 12V?

"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 7 to 12 volts."

Does Arduino Uno R3 have Bluetooth?

It supports wireless serial communication over Bluetooth® (but is not compatible with Bluetooth® headsets or other audio devices).

Can I use pin 0 and 1 Arduino?

That's why digital pin 0 and digital pin 1 of Arduino UNO is normally avoided for the projects. But we can definitely use the digital pin 0 and digital pin 1 as a digital input-output pin after uploading the program or sketch to the Arduino board.

Why PWM is used in Arduino?

PWM Examples Providing an analog output; if the digital output is filtered, it will provide an analog voltage between 0% and 100%. Generating audio signals. Providing variable speed control for motors. Generating a modulated signal, for example to drive an infrared LED for a remote control.

What is VCC in Arduino?

(Vcc is the regulated DC supply voltage needed to operate an IC and is often referred to as a supply voltage for ICs.) Most commonly, Arduinos are designed to work at either a 3.3 V level logic for low power consumption or 5 V logic to be compatible with legacy TTL logic devices.

What are the major components of the Arduino Uno r3 board?

The major components of Arduino UNO board are as follows:

USB connector.
Power port.
Microcontroller.
Analog input pins.
Digital pins.
Reset switch.
Crystal oscillator.
USB interface chip.

Why is it called Arduino Uno?

"Uno" means one in Italian and was chosen to mark the release of Arduino Software (IDE) 1.0. The Uno board and version 1.0 of Arduino Software (IDE) were the reference versions of Arduino, now evolved to newer releases.

What is the GND pin used for?

GND (3): Short for 'Ground'. There are several GND pins on the Arduino, any of which can be used to ground your circuit. 5V (4) & 3.3V (5): As you might guess, the 5V pin supplies 5 volts of power, and the 3.3V pin supplies 3.3 volts of power.

Can Arduino output 5V?

Yes, the digital pin can provide 5V. At a very low current. If you connect a load to it, then the voltage will go down.

Can Arduino output more than 5V?

The result is the processor cannot output any more that the input, here 5V. Also know the processor is designed to work at no more than 5.5 Volts so attempting to put 6 or 7 volts on the processor in hopes of getting more voltage out will fail, because the processor will be damaged and stop working.

Is Arduino a microcontroller?

Arduino (/ɑːrˈdwiːnoʊ/) is an open-source hardware and software company, project, and user community that designs and manufactures single-board microcontrollers and microcontroller kits for building digital devices.

Which is better Raspberry Pi or Arduino?

Arduino is considered a very good board for quick programming and circuit prototyping. On the other hand, Raspberry Pi functions as a learning tool for Computer Programming. However, Raspberry is found useful in many DIY projects as well.

Why Arduino Uno is best?

Arduino UNO is a low-cost, flexible, and easy-to-use programmable open-source microcontroller board that can be integrated into a variety of electronic projects. This board can be interfaced with other Arduino boards, Arduino shields, Raspberry Pi boards and can control relays, LEDs, servos, and motors as an output.
