Usage

Basic Functionality

The Crash Sensor is a simple Single Pole Single Throw Switch (SPST). When the sensor is not press, the electrical path through it is "open" (electrons cannot flow through it). When the sensor is pressed, the electrical path through it is "closed" (electrons can flow through it). It is an input module which produces a HIGH or LOW voltage depending if pressed or not. A Core module can read the voltage value and determine the state of the Crash Sensor.

The LED Trinket is a simple trinket which emits light when passed with a sufficient voltage. A Core module can supply voltage to the LED Trinket.

Programming

//Define the pin the sensor is connected to
const int LED_PIN = 6;

void setup() {
  // put your setup code here, to run once:

  //Initial serial communication port at 9600 baud
  Serial.begin(9600);

  //Configure the pin into output mode
  pinMode(LED_PIN, OUTPUT);
}

void loop() {
  // put your main code here, to run repeatedly:

  //Perform a digitalWrite with HIGH to turn on LED
  digitalWrite(LED_PIN, HIGH);

  //Delay 1 second
  delay(1000);

  //Perform a digitalWrite with HIGH to turn on LED
  digitalWrite(LED_PIN, LOW);

  //Delay 1 second
  delay(1000);
}
