If a voltage is provided through a power jack, it can be accessed through this pin. It is different than 5 V supplied through a USB port. It is the input voltage provided to the Arduino Board. Providing HIGH value to the pin will turn it ON and LOW will turn it OFF. Arduino Uno comes with a built-in LED which is connected through pin 13. However, too much increase in current makes these resisters useless and damages the device. Internal pull-up resistors are used in the board that limits the current exceeding the given operating conditions. These pins come with standard operating ratings ranging between 20mA to 40mA. There are several I/O digital and analog pins placed on the board which operates at 5V. The following figure shows the pinout of the Arduino Uno Board. A 16 MHz frequency crystal oscillator is equipped on the board. ON-chip ADC is used to sample these pins.
Arduino Board comes with 14 digital pins and 6 analog pins. This controller comes with 2KB SRAM, 32KB of flash memory, 1KB of EEPROM.
Only 5 V is required to turn the board on, which can be achieved directly using a USB port or external adopter, however, it can support an external power source up to 12 V which can be regulated and limit to 5 V or 3.3 V based on the requirement of the project.Īrduino Uno is based on an AVR microcontroller called Atmega328. 
These pins measure from 0 to 5V, however, they can be configured to the high range using analogReference() function and AREF pin.
The 6 analog pins are marked as A0 to A5 and come with a resolution of 10bits. Simply plug the external device into the pins of the board that are laid out on the board in the form of the header. There is no hard and fast interface required to connect the devices to the board. These pins provide flexibility and ease of use to the external devices that can be connected through these pins. There are 14 I/O digital and 6 analog pins incorporated in the board that allows the external connection with any circuit with the board. This pin is useful when the board hangs up in the middle of the running program pushing this pin will clear everything up in the program and starts the program right from the beginning. A reset pin is present in the board that resets the whole board and takes the running program in the initial stage. This board comes with a built-in regulation feature that keeps the voltage under control when the device is connected to the external device. It is an open-source platform where anyone can modify and optimize the board based on the number of instructions and tasks they want to achieve. Atmega328 microcontroller is placed on the board that comes with a number of features like timers, counters, interrupts, PWM, CPU, I/O pins and based on a 16MHz clock that helps in producing more frequency and number of instructions per cycle. #Arduino uno pinout schematic serial#
USB port is added on the board to develop serial communication with the computer. Arduino Uno comes with a USB interface i.e.Apart from USB, a battery or AC to DC adopter can also be used to power the board.

You can download the Arduino UNO datasheet by clicking the below button:. Arduino UNO supports 3 types of communication protocols, used for interfacing with third-party peripherals, named:. Arduino UNO comes with 3 types of memories associated with it, named:. PWM pins in Arduino UNO are D3, D5, D6, D9, D10 and D11. Out of 14 digital pins, 6 pins are used for generating PWM pulses of 8-Bit resolution. It also has 6 Power Pins, which provide different voltage levels. In order to reset the board, we need to make this pin LOW. It also has 1 Reset Pin, which is used to reset the board programmatically. It also has 6 analog pins starting from A0 to A5. Arduino Uno Pinout consists of 14 digital pins starting from D0 to D13. It comes with a crystal oscillator of 16MHz, which is its operating frequency. Arduino UNO has a maximum current rating of 40mA, so the load shouldn’t exceed this current rating or you may harm the board. It has an operating voltage of 5V while the input voltage may vary from 7V to 12V. #Arduino uno pinout schematic software#
The software used for writing, compiling & uploading code to Arduino boards is called Arduino IDE (Integrated Development Environment), which is free to download from Arduino Official Site.Arduino Uno is a microcontroller board, developed by, based on the Atmega328 microcontroller and is marked as the first Arduino board developed(UNO means “one” in Italian).I’ll try to cover each and everything related to Arduino Uno, so you get a clear idea of what it does, its main features, working and everything you need to know.
