8. Seal Temperature: 250°-280°.
Key switch module and a digital interface, built-in 13 LED build a simple circuit to produce key warning lamp.13 comes with digital interfaces of the LED,
theaccess number 3 button switch sensor interfaces, when the key switch sensor senses a key signal , LED lights , otherwise off.


Routines Source Code:
int Led=13;// Definition LED Interface
int buttonpin=3 // Define the key switch sensor interface
int val;// Defines a numeric variable val
void setup()
{
pinMode(Led,OUTPUT);// Definition LED as output interface
pinMode(buttonpin,INPUT);// Defined the button switch sensor as the output interface
}
void loop()
{
val=digitalRead(buttonpin);// The digital interface is assigned a value of 3 to read val
if(val==HIGH)// When the key switch test the sensor detects a signal , LED flashes
{
digitalWrite(Led,HIGH)
}
else
{
digitalWrite(Led,LOW)
}
}
