Arduino Introduction

Arduino

The Arduino microcontroller has quickly become a favorite of both hobbyists and professionals. 
It’s a popular platform for creating many different types of automated systems
To control the Arduino, you need to know the Arduino programming language. 
The Arduino programming language derives from the C programming language, with some added features unique to the Arduino environment. 
However, beginners sometimes find the C programming somewhat tricky to navigate.

void setup() {
  // initialize digital pin LED_BUILTIN as an output.
  pinMode(LED_BUILTIN, OUTPUT);
}

// the loop function runs over and over again forever
void loop() {
  digitalWrite(LED_BUILTIN, HIGH);               // turn the LED on (HIGH is the voltage level)
  delay(1000);                                                    // wait for a second
  digitalWrite(LED_BUILTIN, LOW);                // turn the LED off by making the voltage LOW
  delay(1000);                                                    // wait for a second
