Schematics

Circuit Schematic

The 4x4 Membrane Switch (Keypad) utilizes eight wires for eight different connections to the particle argon (4 rows, 4 columns). These wires should be connected from the keypad to the argon's data pins from D1 to D8. The shorter leg of the red LED should be wired to ground. The longer leg of the red LED should be connected to 3.3V positive and in series with the 220 ohm resistor and the D9 argon data pin. The other end of the 220 ohm resistor should be wired to ground.

Code

Code for iRockPaperScissors Game

Arduino
The software used to create the code was the build.particle.io website. The website should also be connected to the particle argon via wifi to be able to flash the code created to the parrticle argon.
#include <Keypad_Particle.h>

const int ROW_NUM = 4; //four rows
const int COLUMN_NUM = 4; //4 columns

int led1 = D9; // Instead of writing D9 over and over again, we'll write led1
// You'll need to wire an LED to this one to see it blink.



char keys[ROW_NUM][COLUMN_NUM] = {
  {'1','2','3','A'},
  {'4','5','6','B'},
  {'7','8','9','C'},
  {'*','0','#','D'}
};

byte pin_rows[ROW_NUM] = {8, 7, 6, 5}; //connect to the row pinouts of the keypad
byte pin_column[COLUMN_NUM] = {4, 3, 2,1}; //connect to the column pinouts of the keypad

Keypad keypad = Keypad( makeKeymap(keys), pin_rows, pin_column, ROW_NUM, COLUMN_NUM );


void setup() { 

  Serial.begin(9600);
  //For your project you can change "keypressedharrison" to "keypressed____" and insert your name or any other word.
  Particle.variable("keypressedharrison",keys[ROW_NUM][COLUMN_NUM]);
  
   // Configure the pins to be outputs
   pinMode(led1, OUTPUT);

 
   
      //Register our Particle function here
   Particle.function("led", ledControl);
}

void loop(){
 
  char key = keypad.getKey();
if (key){
    Serial.println(key);
     //For your project you can change "keypressedharrison" to "keypressed____" and insert your name or any other word.
    Particle.publish("keypressedharrison", String(key), PUBLIC);

  }
}


int ledControl(String command)
{

   // find out the state of the led
   // you can write any word instead of "LOW". This is simply the command used to trigger your function. 
   if(command == "LOW"){
	   digitalWrite(led1, LOW);
	   delay (1000);
	   digitalWrite(led1,HIGH);
   }

}
