Mercury switch module and digital 13 interface with LED to build a simple circuit to produce tilting lights
As the digital 13 interface comes with an LED, the mercury tilt switch sensor is connected to the digital 3 interface. When the mercury tilt switch sensor has a button signal, the LED light is on, and vice versa.
Regular source code:
Int Led = 13; //Define the LED interface
Int buttonpin = 3; //Define the mercury tilt switch sensor interface
Int val; / / define the numeric variable val
Void setup()
{
pinMode (Led, OUTPUT); / / define the LED as an output interface
pinMode(buttonpin, INPUT); // Define the mercury tilt switch sensor as the output interface
}
Void loop()
{
Val = digitalRead(buttonpin); //Write the value of digital interface 3 to val
If(val == HIGH)//The LED flashes when the mercury tilt switch sensor detects a signal
{
digitalWrite(Led,HIGH);
}
