feature

  • Special module with ports compatible with the expansion board of sensor.
  • Output low level when the module is activated; keep outputting high level at the state of release.
  • Applied in the detection of collision and touching impact.

Experimental Procedures For Arduino

Step 1: Connect the circuit:

Creshsensor Uno Board
VCC 5V
GND GND
D0 2

Collision Switch Module(Fritzing).png
Step 2: Compile and upload the code Using SunFounder Uno 

int ledPin = 13;                // choose the pin for the LED
int inputPin = 2;               // Connect sensor to input pin 3


void setup() {
  Serial.begin(9600);           // Init the serial port

  pinMode(ledPin, OUTPUT);      // declare LED as output
  pinMode(inputPin, INPUT);     // declare Micro switch as input
}

void loop(){
  int val = digitalRead(inputPin);  // read input value
  if (val == LOW) {                // check if the input is HIGH
digitalWrite(ledPin, HIGH);      // turn LED ON
Serial.println("Switch Pressed!");
  } else {
    digitalWrite(ledPin, LOW);     // turn LED OFF 
  }
  delay(50);
}

When the module detects the impact, the serial port will output “Switch Pressed!”Meanwhile, the LED on the pin 13 of the UNO board will light up.
