KEYES ARDUINO digital temperature module

Digital temperature module and a digital interface, built-in 13 LED build a simple circuit, making the temperature warning lamp 13 comes with digital interfaces of the LED, the digital temperature sensor connected digital three interfaces, when the digital temperature Sensor senses a key signal, LED lights, otherwise off.

Example Code

int Led = 13 ; // define LED Interface
int buttonpin = 3; // define the digital temperature sensor interface
int val ; // define numeric variables val
void setup ()
{
  pinMode (Led, OUTPUT) ; // define LED as output interface
  pinMode (buttonpin, INPUT) ; // define digital temperature sensor output interface
}
void loop ()
{
  val = digitalRead (buttonpin) ; // digital interface will be assigned a value of 3 to read val
  if (val == HIGH) // when the digital temperature sensor detects a signal, LED flashes
  {
    digitalWrite (Led, HIGH);
  }
  else
  {
    digitalWrite (Led, LOW);
  }
}
