Tilt Sensor

Overview

Based on the SW-460D ball switch digital module, the use of steel ball characteristics, through the action of gravity that ball to low rolling, thus making the switch closed or disconnect, so also can be used as a simple angle sensor use.

Ball switch digital input module, and arduino special sensor expansion board combination, will be able to realize the very interesting interactive works, than using mercury switch more safety.

Programming

The program below uses the tilt sensor to control the LED.

Sample code：

<syntaxhighlight lang="c">

int ledPin = 13; // Connect LED to pin 13 int switcher = 3; // Connect Tilt sensor to Pin3

void setup() {

 pinMode(ledPin, OUTPUT);      // Set digital pin 13 to output mode
 pinMode(switcher, INPUT);       // Set digital pin 3 to input mode

} void loop() {

  if(digitalRead(switcher)==HIGH) //Read sensor value
    { 
       digitalWrite(ledPin, HIGH);   // Turn on LED when the sensor is tilted
    }
  else
    {
       digitalWrite(ledPin, LOW);    // Turn off LED when the sensor is not triggered
    }

}
