But we can use only one function of each pin at a time. Pinout diagram shows that each pin has multiple functions such as PWM, interrupts, general-purpose input-output and analog channel.

This is actually the beginning of the journey of Arduino learning. Not This is the very basic project on Arduino.We can do many fascinating things using Arduino. The following figure shows the Arduino UNO Pinout for better understanding: How to Program Arduino UNOAccording to arduino.cc -> Arduino is an open-source electronics platform based on easy-to-use hardware and software. There is a range of Arduino boards available in the market but the Arduino UNO is the most common board used in the electronic industry. At first you use mainly the pins in the female. While this pinout is a good start, it does not explain the complete story but it does give a good beginning. Education 3 days ago ARDUINO UNO Revision 3 Pinout (Uno PCB) Commonly Used Features are printed on Silkscreen The Arduino Uno pinout is printed in the silkscreen on the top of the part.
![]() These PWM pins can be used as Analog pin.ATmega16U2 instead 8U2 as USB-to-Serial converter. Form the 14 digital pins there are 6 PWM pins also available. It consists 14 Digital I/O pins and 6 Analog pins. This is very simple to learn. Arduino UNO depends on ATmega328P based microcontroller. Arduino UNO is the most frequently used Arduino board. Red one indicates that we need to connect the positive terminal of battery or any kinds of power supply. Flash Memory: 32 KB, and 0.5 KB memory is used by the boot loaderHere, A & D are two power rails. PWM Digital I/O Pins: 6 (D3, D5, D6, D9, D10, D11) In B section vertical lines are short from one point to another point. These two sections are separated by each others. B & C are the circuit building area. Technics sl bd20d manualThese 2 led's Anode is connected with the resistor and Cathode is connected with the negative terminal of power rails of breadboard.Here, Arduino Board is used only for the power supply. Here, resistors are user for the protection of the led lights. In the C section also 24 lines are individually short in the vertical direction.From the schematic diagram we can see that the two led(Green and Orange) are connected with power rail via a 220ohm resistor. 24 lines are individually short in vertical direction. Here a the 5V willl not flow through the LEDs because of the voltage drop for the resistors. Then the power will go through the LEDs through resistor. We can measure the voltage by using a multimeter.So, when we turn ON the arduino that means when we power up the Arduino UNO board we will get the 5V supply in the breadboard instantly. So, here from Arduino 5V is supplied to the breadboard. In this project we did not use any Arduino coding.
