### Arduino Blinker Example Tutorial For beginners learning about microcontrollers, blinking an LED is often one of the first projects undertaken. This project demonstrates how to use a digital output pin on an Arduino board to turn an LED on and off at intervals. The following code snippet shows how to set up and run a simple blink program using Arduino: ```cpp // Pin number where we connect the LED. const int ledPin = 13; // The built-in LED on most Arduino boards is connected to digital pin 13 void setup() { pinMode(ledPin, OUTPUT); // Sets the digital pin as output. } void loop() { digitalWrite(ledPin, HIGH); // Turns the LED on (HIGH is the voltage level). delay(1000); // Waits for a second. digitalWrite(ledPin, LOW); // Turns the LED off by making the voltage LOW. delay(1000); // Waits for a second. } ``` This sketch uses two main functions provided by the Arduino environment: `pinMode` sets whether a pin operates as an input or output, while `digitalWrite` sends a high or low signal to a specified pin[^1]. To upload this script onto an Arduino device requires installing drivers specific to your operating system along with configuring settings within the Arduino Integrated Development Environment (IDE). For ESP-based modules like esp32c3, ensure that additional board manager URLs are added correctly according to official guidelines[^3].
