Alright since now we know how to interface a LED let’s have some fun generating patterns with multiple LED. Components Required Resistor                    4 No. 330Ohms(Standard Red LED and 5V input supply) LEDs                        4 No. Arduino UNO          1No. Connecting wires Breadboard In this blog, we have generated a shifting glowing pattern of LEDs. For circuit, connections see below After building the circuit dump the code given below. int led1 = 1; int led2 = 2; int led3 = 3; int led4 = 4; void setup()  { pinMode(led1, OUTPUT); pinMode(led2, OUTPUT); pinMode(led3, OUTPUT); pinMode(led4, OUTPUT); } void loop() { digitalWrite(led1, HIGH); // turn the LED on (HIGH is the voltage level) delay(500); digitalWrite(led1, LOW); // turn the LED off by making the voltage LOW delay(500); digitalWrite(led2, HIGH); // turn the LED on (HIGH is the voltage level) delay(500); digitalWrite(led2, LOW); // turn the LED off by making the voltage LOW delay(500); d

Now since we know how an Arduino works let us have some fun with the board. For those of you who are new kindly have a look at the link given below. http://sudolearn.blogspot.com/2017/05/getting-started-with-arduino.html Let us first design a smart led blinking system which will blink how we want it to, sounds fun right. So let’s begin Components Required Resistor                        1No.  330ohms (Standard Red LED and 5V Input) Led                               1No. Arduino UNO              1No. Few Connecting wires Breadboard Follow the below video for circuit connection reference: Now since we have made the circuit let us do the coding part // declare the pin to which LED is connected: int led = 5;  //The below is the setup block the part which we want to run only once we declare them in this block void setup() // initialize the digital pin as an output. { pinMode(led, OUTPUT); } void loop() //The code we write inside void loop

What is Arduino? Arduino is basically an open source electronics platform which is having easy to use hardware and software implementation. It’s a micro-controller interfaced with other vital components like programmer ICs, voltage regulator etc. With the help of this, we can interface various input (sensors) and output (LED's) components. Why Arduino? Arduino is not just a micro-controller it is also interfaced with several other components which make the job of the user very simple. Arduino Uno Pin-Out How Arduino works? An input of 5v is given to the board using a USB cable (not necessary) through a laptop or any other convenient power source. Microcontrollers are usually programmed through a programmer unless we have a firmware in our microcontroller that allows installing new firmware without any external programmer. This is bootloader. All the controllers present in UNO are from ATMEL Semiconductor (Now acquired by Microchip). We hav
