Story

When I take Ajax (our dog) to the park, sometimes he gets distracted and runs off. Usually to do something dignified like sniffing garbage. Now, I can open the browse on my phone to the BuzzWolf webpage and press the "Buzz" button. Using the Particle Electron 3G board, his collar (connected to the 3G cellular network) vibrates for a moment. This is enough to snap him out of whatever it is he's doing. It's kind of like having somebody tap you on the shoulders. It's a painless way to get his attention when he's off leash and out of earshot.

The circuit is simple. The three vibrating discs has a positive and negative. The negative wires all connect to Particle Electron's ground, and the positives connect to D5, D6, and D7 pins. I made a little header for the board.

Here's a video of it working. It's on top of my Surface, which displays the front end webpage with the big ol' buzz button.

I then used Blue Painter's Tape to hold this contraption together, and made a pouches for this contraption and the battery.

Sewing pouches

Making sure the battery's pouch was the right size (do not sew with battery on the machine!)

Pouches done! Battery pouch on left, contraption pouch on right

I then took everything out of the pouches, and sewed the pouches to a dog collar.

Ta da!!

Code

// Pin numbers for vibrating discs
int vib1 = D7;
int vib2 = D6;
int vib3 = D5;

void setup()
{
   // Set pins to output, meaning info flows from particle to component (vibrating discs)
   pinMode(vib1, OUTPUT);
   pinMode(vib2, OUTPUT);
   pinMode(vib3, OUTPUT);

   // Method, buzz is the URL method that the front end calls, and buzzToggle is the 
   // function within this particle code (see below)
   Spark.function("buzz",buzzToggle);
   
   // Set vibration to low, so the vibrating discs don't vibrate at startup
   digitalWrite(vib1, LOW);
   digitalWrite(vib2, LOW);
   digitalWrite(vib3, LOW);

}


void loop()
{
   // Nothing to do here :)
}


int buzzToggle(String command) {
    if (command=="blip") {
        digitalWrite(vib1,HIGH);
        digitalWrite(vib2,HIGH);
        digitalWrite(vib3,HIGH);
        delay(1000);
        digitalWrite(vib1,LOW);
        digitalWrite(vib2,LOW);
        digitalWrite(vib3,LOW);
        return 2;

    else if (command=="test") {
        return 3;
    }
    else {
        return -1;
    }
