  How to Blink LED Infinitely Using Arduino and Proteus: A Step-by-Step Guide Blinking LED is one of the simplest yet most rewarding projects for anyone starting with Arduino. In this tutorial, we’ll guide you through the process of creating an infinitely blinking LED circuit using Arduino and simulating it in Proteus. Whether you’re a beginner or an enthusiast, this project will enhance your skills in coding, circuit design, and simulation. Why Blink an LED? Blinking an LED is often the first step in learning Arduino programming. It introduces key concepts such as pin configuration, digital output, and delays. Simulating the project in Proteus adds another dimension by allowing you to visualize the circuit without physical hardware. What You’ll Need Here’s a list of components and software required for this project: Hardware: Arduino Uno LED (any color) Resistor (e,g 70Ω, 220Ω or 330Ω etc. Check how to calculated the LED protective resistance 👉 HERE ...

 Interfacing a Light Emitting Diode (LED) with Arduino What is a LED? A light-emitting diode (LED) is a semiconductor device that produces light when an electric current flows through it. Applications: Indicators, Displays such as Matrix display, Led bulbs etc. Proteus Circuit of Turning on LED Arduino Code void setup() {   // put your setup code here, to run once: pinMode (7,OUTPUT);   // pin 7 (LED pin) configured as an output digitalWrite(7,HIGH);    // command to turn ON LED  } void loop() {   // put your main code here, to run repeatedly: }   Arduino Code for Turning ON/OFF LED Twice void setup() {   // put your setup code here, to run once: pinMode (7,OUTPUT);   // pin 7 (LED pin) configured as an output digitalWrite(7,HIGH);     // command to turn ON LED  delay(1000);                  // command for a 1 second delay digitalWrite(7,LOW);    // co...
