Công thức toán học

<math> 

 \operatorname{erfc}(x) =
 \frac{2}{\sqrt{\pi}} \int_x^{\infty} e^{-t^2}\,dt =
 \frac{e^{-x^2}}{x\sqrt{\pi}}\sum_{n=0}^\infty (-1)^n \frac{(2n)!}{n!(2x)^{2n}}

</math>

$ 

 \sum f(x) = F(x) + g(x)

  Blink
  Turns on an LED on for one second, then off for one second, repeatedly.
 
  This example code is in the public domain.

// Pin 13 has an LED connected on most Arduino boards.
// give it a name:
int led = 13;

// the setup routine runs once when you press reset:
void setup() {                
  // initialize the digital pin as an output.
  pinMode(led, OUTPUT);     
}

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