The Crash Sensor is a simple switch 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.

  • General Pin Out is the standard pin out of a Sensor / Trinket connector.
  • Sensor / Trinket's Pin Out is this specific Sensor / Trinket's wiring in relation to the General Pin Out.
  • SIGNAL-A / SIGNAL-B are signals that could be digital input, digital output, analog input or analog output. Or special signals such as serial communication (SoftwareSerial, IIC (I2C), etc) or other special signals.
  • Not Connected refers to the Pin not being used for this particular Sensor / Trinket.

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.

Programming

Introduction

The Crash Sensor is used as a simple input pin. Therefore, the pinMode, digitalRead functions will be used.

Key Functions

  • Required Libraries: None
  • Key Functions
    • pinMode(pin_number, pin_mode)
      • pin_number - is the pin number that the sensor is connected to.
      • pin_mode - is the mode to set the pin to. Either INPUT or OUTPUT
    • digitalRead(pin_number)
      • pin_number - is the pin number that the sensor is connected to.

Note: Important lines of code are highlighted 

#include <iostream>
void function(int i){
int pinNum = 10;
	digitalWrite(pinNum, HIGH);
	delay(10);
	digitalWrite(pinNum, LOW);
}
