Differences between the A, CNAME, ALIAS and URL records

Differences between the A, CNAME, ALIAS and URL records

•    The A record maps a name to one or more IP addresses, when the IP are known and stable. 當IP已知且穩定時，A記錄將名稱映射到一個或多個IP地址

•    The CNAME record maps a name to another name. It should only be used when there are no other records on that name. CNAME記錄將名稱映射到另一個名稱。 只有在沒有其他記錄的情況下才能使用。

•    The ALIAS record maps a name to another name, but in turns it can coexist with other records on that name. ALIAS記錄將名稱映射到另一個名稱，但是它可以與該名稱上的其他記錄共存。

•    The URL record redirects the name to the target name using the HTTP 301 status code.

LED 長腳接+: Pin 13

Load Blink template:

// the setup function runs once when you press reset or power the board

void setup() {

  // initialize digital pin LED_BUILTIN as an output.

  pinMode(13, OUTPUT);

}

// the loop function runs over and over again forever

void loop() {

  digitalWrite(13, HIGH);   // turn the LED on (HIGH is the voltage level)

  delay(200);                       // wait for a second

  digitalWrite(13, LOW);    // turn the LED off by making the voltage LOW

  delay(1000);                       // wait for a second

int led = 9;           // the PWM pin the LED is attached to Pin 9具備 PWM功能
int brightness = 0;    // how bright the LED is

// the setup routine runs once when you press reset:
void setup() {
  // declare pin 9 to be an output:
  pinMode(led, OUTPUT);
}

// the loop routine runs over and over again forever:
void loop() {
  // set the brightness of pin 9:
  analogWrite(led, brightness);

  // change the brightness for next time through the loop:
