From 0 to 13 used as general-purpose digital in/out has internal pull-up resistors that can be high/low to ON/OFF maximum current per pin 40 mA.Īs showing in fig A from D0 to D13 pins. We use 14 digital pins as input or output. We cannot use less than o and over 5 volts for the AREF Pin. AREF is used to set external analog input voltage. We use an analog reference pin for analog reference. Analogwrite function () is very effective to operate the DC motors and varying led light in many electronic projects. Pin # 3, 5, 6, 9, 10, and 11 used for PWM function (Pulse Width Modulation). Pin 2 & 3 can use as INT0 & INT1, we can configure it to act as external interrupts for a function written in the program. RX is to receive data, and TX to transmit the data.

Pin 0 used as RX and 1 TX (in fig-A as D0&D1)used for TTL Serial Communication. A Wire library is available to communicate with different devices with the Arduino board. We use it for I☬ (inter integrated-circuit) / TWI (two-wire interface) communication. It contains 06 ADC (analog-to-digital converter)with a 10-bit resolution. These Arduino pins have the functionality of general-purpose digital in/out pins. Pin A0 to A5 Used as analog input pins (for Sensors modules) used as analog output. We can use a 9V battery cell for the input supply voltage. It uses Vin pin for 7-12 VDC apply to the board as an external power source.

These pins could be GPIO or using for specific signals. Blue color represents Power pins, Pink for analog input pins, Light blue for Digital pins, Green for communication, and Purple for PWM pins.Īrduino UNO board has analog/digital (PWM) pins. The Arduino board requires only 5V DC to operate.Īrduino Pins color shows pin functions. To program the main chip, a 16 MHz crystal is part of the board. The Atmega328P Microcontroller is an 8bit with 32k byte internal flash memory. Arduino also manufactured IoT (internet of things), Bluetooth, GSM/3G, Wi-Fi, and motion sensors boards. If you are getting any trouble while working on it then ask in the comments and I will help you out.Arduino UNO Pinout and Board descriptionI will explain the description of the Arduino UNO Pins and the board in the post. Arduino Uno is a standard board of the company, even though other boards e, g. I must add it's just the tip of the iceberg and there's a lot we can do with this Microcontroller board. So you must have got the picture of its uses. A few of its working fields are as follows: It's the most commonly used Microcontroller board.

A bootloader of 2Kb is installed so we are left with 30kb Flash memory.Īrduino UNO has numerous applications in our everyday life.

So, let's have a look at its memory features:

#Arduino uno pinout reference code

If you have bigger data or code etc to save then you shouldn't select this one, I would recommend Arduino Mega. Memories are of main concern while selecting a microcontroller for your project.

We can also design software serial as well. If you want to use SPI modules then you have to stick to SPI Pins and if you want to interface Serial modules like GSMm or GPS then you need to use Serial Pins. So, these digital and analog pins are capable of multiple functions and it totally depends on your project's requirement.

Arduino UNO supports follow 3 communication protocols:.

It also has 6 PWM pins which are used for Pulse Width Modulation.

Among these 20 pins, we have 14 digital pins.

If you are working on some project and you want to use this Arduino UNO board then you should know about its Pinout.

Anyone can design its Libraries for different sensors and modules.Arduino is an open-source platform so it has a lot of support from third-party developers.Arduino Bootloader is installed on Atmega328 which makes it capable to work with Arduino Programming.It used an Atmega328 Microcontroller which acts as the brain of this board.Arduino UNO is a Microcontroller board designed by in Italy.Let's have a look at the basic details of Arduino UNO: So, let's cover this one from the basics: You should have a look at the Arduino UNO Pinout Diagram if you are planning to start working on this microcontroller board. You can design its libraries for different sensors etc. I really admired the idea as they have kept everything open source. Arduino UNO is the most commonly used Microcontroller board designed by in Italy. In today's tutorial, I am going to share all the basic details about Arduino UNO. Hello friends, I hope you all are doing great.
