Blink LED: Arduino, ESP32, STM32, LPC2148, PIC16f877a
Here's a simple "Blink LED" code example for various microcontroller platforms along with explanations for each. This example will make an LED connected to a digital pin blink on and off. Arduino (Using Arduino IDE and Arduino Uno): int ledPin = 13; // LED connected to digital pin 13 void setup() { pinMode(ledPin, OUTPUT); // Set the LED pin as an output } void loop() { digitalWrite(ledPin, HIGH); // Turn the LED on delay(1000); // Wait for 1 second digitalWrite(ledPin, LOW); // Turn the LED off delay(1000); // Wait for 1 second } Explanation for Arduino: - The LED is connected to pin 13. - In the `setup()` function, we set `ledPin` as an output using `pinMode()`. - The `loop()` function alternates between turning the LED on and off using `digitalWrite()` and introduces delays using `delay()` to control the blinking rate.
