Custom parts and enclosures

Buzz Wire Game Course Stand

This is the main base portion of the stand for the buzz wire game. This portion can be specific to what type of course you make so if you would like to use this make sure your course will fit its dimensions.

Buzz Wire Game Wire Locker Course

This is what lockes down one end of the course to keep it from coming out of the main case

Buzz Wire Game Insulator

This is what insulates the end of the wire so you can rest the handle down on one end and it wont keep touching the hot (course) wire.

Code

Buzz Wire Game Code

C/C++
This is the code to be deployed to your Dot One for the Buzz Wire Game
#include <WiFi.h>
#include <Wia.h>

const int inputWirePin = 19;
const int outputWirePin = 18;
const int buzzerPin = 26;
int previousTime1 = 0;
int previousTime2 = 0;
int timeElapsed1 = 0;
int timeElapsed2 = 0;
bool stop;

Wia wiaClient = Wia(); // this is necessary for the Dot One to funtion properly

void setup()
{
  WiFi.begin(); // this connects the Dot One to the wifi
 	delay(2500);
  // this pin is the wire that detects if they have touched
  pinMode(inputWirePin,INPUT_PULLDOWN);
  // this pin is the hot wire meaning it has voltage and will supply current when the two wires touch
  pinMode(outputWirePin,OUTPUT);
  // this pin controls the buzzer
  pinMode(buzzerPin, OUTPUT);
}

void loop()
{
  stop = false;
  digitalWrite(outputWirePin, HIGH); // set the hotwire to high
  if(digitalRead(inputWirePin) == HIGH) // check if the wires have touched
  {
    // this loop allows you to start a run
    previousTime2 = millis();
    while(digitalRead(inputWirePin) == HIGH)// this is responsible for the start run
    {
      delay(1);
      if(millis()-previousTime2 > 4000) // checks that the wires have been connected for 4000ms
      {
        delay(2000); // delay to give time for the user to start
        previousTime2 -= 2000; // deduct the delay form their time
        stop = true; 
        break; // break out of the while loop
      }
    }
    timeElapsed2 = millis()-previousTime2; // calculate the time elapsed 
    if(timeElapsed2 >= 4000)
    {
      for(int i = 0; i < 5; i++)
      {
        digitalWrite(buzzerPin, HIGH);
    		delay(100);
    		digitalWrite(buzzerPin, LOW);
        delay(100);
      }
    }
    if(stop) // this indicates if the run should be started or if the user made a mistake
    {
      wiaClient.createEvent("Start run");
    }
    else
    {
      timeElapsed1 = millis() - previousTime1; // calculate run time
      previousTime1 = millis();
      wiaClient.createEvent("End run", timeElapsed1); // print run time 
      digitalWrite(buzzerPin, HIGH); // buzz when the user touched
      delay(100);
      digitalWrite(buzzerPin, LOW);
      delay(3000);
    }
  }
}
