Story

Introduction

This project is for an instrumentation class at the University of North Carolina at Charlotte. The task presented to the class was to build and program a device that uses IoT to communicate between two particle boards. Other than that the rubric left the actual project up to each groups discretion. My partner for the project and I both enjoyed playing with those indoor basketball hoops when we were younger and during the brainstorming of ideas we came up with the idea to make those cooler and more fun. We thought, what if the indoor basketball hoops could keep score and display it behind the backboard? Thus, Smart Hoop was born.

Score

This Project started with the purchase of a clear backboard to protect the LED's from being hit by the basketball. The sensor used was a button sensor connected to a photon that sends a score to the cloud when triggered by the basketball going through the hoop. The SMARTHOOP code also counts the scores up to five and is reset afterwards. The second photon runs the SMARTHOOP_LED code and receives the data from the cloud and displays the code by activating the LEDs. To see the demonstration of the smart hoop click the video below.

The sensor is secured to the backboard by the adhesive on the back of the breadboard. This is also how the LEDs are attached. A detailed view of the attached breadboards can be seen in the following video.

Smart Hoop, if sold as a set can bring your children hours of play with a touch of competitiveness. Turn off the lights and the game becomes even more fun as the array of lights brighten the room and transform a ordinary game into something extraordinary. The Smart Hoop is also able to track the time of the game as seen in figure 2. This is done by using a graphing program to log the time of each score.

Code

// Our button wired to D0
int buttonPin = D0;
int score=0;
char myString[1];

void setup()
{

  // For input, we define the
  // pushbutton as an input-pullup
  // this uses an internal pullup resistor
  // to manage consistent reads from the device

  pinMode( buttonPin , INPUT_PULLUP); 
  


 
 Particle.variable("score", &score, INT);
}

void loop()
{
  int buttonState =( digitalRead( buttonPin ));{ 
    if( buttonState == LOW )
  {delay(2000);
     
      score=score+1;
      sprintf(myString,"%u",score);
      if(score>=6){score=0;}
       Particle.publish("score",myString);
  }

  }
