If you're just getting started with Arduino, this is one of the best places to begin. The Arduino Uno already has a built-in LED connected to digital pin 13, so we don't even need a breadboard or external components. Upload this code: ********************************************** void setup() { pinMode(LED_BUILTIN, OUTPUT); } void loop() { digitalWrite(LED_BUILTIN, HIGH); delay(1000); digitalWrite(LED_BUILTIN, LOW); delay(1000); } **************************************** That's it! 🔥 The LED will: 💡 Turn ON for 1 second ⚫ Turn OFF for 1 second 🔁 Repeat continuously But this tiny program teaches several important Arduino concepts: 🔹 setup() — runs once when the Arduino starts 🔹 loop() — repeats continuously 🔹 pinMode() — configures a pin 🔹 digitalWrite() — controls an output 🔹 HIGH / LOW — turns the output ON or OFF 🔹 delay() — pauses the program for a specified time Try changing: delay(1000); to: delay(200); What happens? 😁 Experiment with different values and watch how the blink rate changes. Sometimes the best way to learn electronics is simply to BUILD something and start changing things. ⚡ CircuitWorks Lab BUILD • TEST • TROUBLESHOOT
