Lane Tech HS - PCL - Mario Pipe(Prototype)

Its a me, Gavin! and I used a particle Argon to move Mario up and down a pole dependent on the Stock price on Nintendo. #FreeMelle

Source Code

C/C++
This is the code used to connect all the dots(API to the Webhook To the Particle to the Servo)
// This #include statement was automatically added by the Particle IDE.
#include <ArduinoJson.h>

// The number below has to be updated to the correct doc size
// Use the official ArduinoJSON Assistant below:
// https://arduinojson.org/v6/assistant/
StaticJsonDocument<200> doc;

Servo myservo;  // create servo object to control a servo
                // a maximum of eight servo objects can be created

int pos = 0;    // variable to store the servo position
float currentPrice=0; // variable to store the the current price
float oldPrice = 0; ; // variable to store the the past price

void setup()
{
    myservo.attach(D8);  // attaches the servo on the D0 pin to the servo object
    // Subscribe to the webhook response event
    Particle.subscribe("hook-response/StockPrice", myHandler, MY_DEVICES);
    Serial.begin(9600);
}

void loop()
{
  String data = String(10);// Get some data
  Particle.publish("StockPrice", data, PRIVATE); // Trigger integration
  delay(60000);// Wait 60 seconds
}

void myHandler(const char *event, const char *data)
{
    float price =atof(data);//ask the API for the price of NTDOY

    float oldPrice = currentPrice;//when the price changes changes, old price becomes the new price 
    float currentPrice = price;//the value pulled by the API becomes currentPrice
    
    if(currentPrice > oldPrice)
    {
       int pos = (currentPrice - oldPrice) * 10;//sets position of the servo 
        myservo.write(pos);// moves servo and moves Mario up
        delay(200);
    }
  
   if(currentPrice < oldPrice)
    {
       int pos = (oldPrice - currentPrice) * -10;;//sets position of the servo 
        myservo.write(pos);// moves servo and moves Mario down
        delay(200);
    }
}
