Description：
Tilt switch module and a digital interface, built-in 13 LED build a simple circuit to produce tilt warning lamp 13 comes with digital interfaces of the LED,
the tilt switch sensor interface to access digital 3,when the tilt open Off sensor senses a key signal, LED lights, otherwise off.
Routines source code:
int Led = 13 ;// define LED Interface
int buttonpin = 3; // define the tilt switch sensor interfaces
int val ;// define numeric variables val
void setup()
{
pinMode(Led, OUTPUT) ;// define LED as output interface
pinMode(buttonpin, INPUT) ;// define the output interface tilt switch sensor
}
void loop ()
{
val = digitalRead(buttonpin) ;// digital interface will be assigned a value of 3 to read val
if(val == HIGH) // When the tilt sensor detects a signal when the switch, LED flashes
{
digitalWrite(Led, HIGH);
}
else
{
digitalWrite(Led, LOW);
}
}
