Arduino Series #3 | External LED with Arduino | Build Your First Real Circuit

Welcome to Arduino Series #3! In this video, we'll build our first real Arduino circuit using an external LED, a resistor, and a breadboard. You'll learn: ✅ LED polarity (Anode & Cathode) ✅ Why resistors are important ✅ Breadboard basics ✅ How to connect an external LED ✅ How to control multiple LEDs using Arduino ✅ Build a simple Multi-LED Project By the end of this video, you'll have successfully built and programmed your first external electronic circuit using Arduino. 🛠 Components Used • Arduino Uno • Breadboard • Red LED • Blue LED • White LED • 220Ω Resistors • Jumper Wires • USB Cable 💻 Single LED Code int led = 13; void setup() { pinMode(led, OUTPUT); } void loop() { digitalWrite(led, HIGH); delay(1000); digitalWrite(led, LOW); delay(1000); } 💻 Multi-LED Code int red = 11; int blue = 12; int white = 13; void setup() { pinMode(red, OUTPUT); pinMode(blue, OUTPUT); pinMode(white, OUTPUT); } void loop() { digitalWrite(red, HIGH); delay(1000); digitalWrite(red, LOW); digitalWrite(blue, HIGH); delay(1000); digitalWrite(blue, LOW); digitalWrite(white, HIGH); delay(1000); digitalWrite(white, LOW); } 📚 Arduino Series Video #1 – Blink LED Video #2 – Understanding the Blink Program Video #3 – External LED with Arduino 👍 If you enjoyed the video, don't forget to Like, Share, and Subscribe. 🔔 Turn on notifications so you never miss a new Arduino tutorial. #Arduino #ArduinoUno #ArduinoTutorial #ArduinoForBeginners #Electronics #EmbeddedSystems #Programming #CircuitForge
