You are learning how to use Arduino to build your own projects?Ĭheck out Arduino For Beginners and learn step by step.Īfter watching the video, subscribe to the Robotics Back-End Youtube channel so you don’t miss the next tutorials! > Watch this video as an additional resource to this article: This post is focused on Arduino Uno board, but most of the explanations (except for the pin numbers on the circuit board) are also valid for any other Arduino board. I’ll also give you some examples of sensors/actuators that you can use with each pin functionality. And some tips on how to connect other devices to your Arduino pins.

If you’re starting with Arduino, or if you’re already a software developer and want to learn more about the bridge between software and hardware on an Arduino board, then you’ve come to the right place! In this post I’ll give you a complete and practical overview of the main Arduino Uno pins. In Arduino, used for an auto-voltage selection circuit, but in reality, it operates as an auto.The Arduino Uno board has over 20 pins that you can use for many different applications. To program the Microcontroller, an ICSP pin header is available on the board.

We use atmega16u Microcontroller for USB serial communication interface. We use the CH341A chip in many cheap programmers. USB Communication Interfaceįor USB/Serial communication, we use mostly two chips, CH341A or Atmega16U.ĬH341a has used a USB interface chip for UART communication, It is a standard parallel port, memory parallel port, and synchronous serial (I2C, SPI Communication). We can use these pins, As analog out/we can control the motor at different speeds. Digital write() function used for high/low pins. We use digital out as High or Low even with PWM outputs function. A built-in led function through pin 14 (D13). 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. 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.
