Arduino Gin&Tonic Mixer

Issues:

1. Pumping carbonated drinks is not a good idea! This method typically only yields about half of the expected volume and the liquid comes out uncarbonated due to the separation of the liquid and carbon in the small tube. It's unclear if the size of the tube has any impact on the effectiveness of this method.

2. In order to improve efficiency, bigger pumps are needed. When using a 6-volt pump, it took 2 minutes and 40 seconds to fill a glass. However, increasing the voltage to 9 volts (while stressing the pump) resulted in a significant decrease in time, with the glass being filled in 1 minute and 20 seconds. This represents a 50% improvement in the time it took to fill the glass.

note: make sure your tubes are going too the right location, had an unfortunate experience with a rather powerful mix!

constants won't change. They're used here to set pin numbers:

const int Mixer =  13;             // the number of the Mixer pin
const int Gin =  12;              // the number of the Gin pin
const int ReadyLed =  9;         // Indicates the machine is ready too pour
const int WorkingLed =  8;      // Indicates the machine is currently pouring
const int buttonPin = 2;            // the number of the pushbutton pin

---

Variables will change while program is running

Button setup:
   bool Clicked = false; // Says that the button is currently NOT pressed
   int buttonState = 0;         // variable for reading the pushbutton status, will change too 1 if pressed(bool)

---

Initial setup on start up, this code will run once when the program initionaly stars running.

void setup() {

   Serial.begin(9600);// opens serial port, sets data rate to 9600 bps(Realy only used for testing)
   
   OUTPUT // Voltage will be set to the corresponding value: 5V (or 3.3V on 3.3V boards) for HIGH and 0V for LOW
   
   pinMode(Gin, OUTPUT); 
   pinMode(Mixer, OUTPUT);
   
  // initialize the Gin/Mixer pins as an output:
   pinMode(ReadyLed, OUTPUT);
   pinMode(WorkingLed, OUTPUT);
   
  // initialize the pushbutton pin as an input:
  
   pinMode(buttonPin, INPUT); // Pins are actualy set as INPUT by default, but im keeping this in for clarity.
   
   digitalWrite(ReadyLed, HIGH); // Turns on ReadyLed too indicate that the machine is ready too pour.
   
   // as unintuitive as it might sound setting the Mixer && Gin pins to HIGH will turn the relays of so here we are just making sure the pumps are turned of.
   
   digitalWrite(Mixer, HIGH);
   digitalWrite(Gin, HIGH);
}

void loop() {
  // read the state of the pushbutton value:
  buttonState = digitalRead(buttonPin);
  digitalWrite(Gin, HIGH);
    digitalWrite(Mixer, HIGH);
      
  // check if the pushbutton is pressed. If it is, the buttonState is HIGH:
  if (buttonState == HIGH) {
    // Switch Clicked state:
    Clicked = !Clicked;
  } else {
    Serial.write("hello");
  }
  if (Clicked == true) {
     digitalWrite(WorkingLed, HIGH);
     digitalWrite(ReadyLed, LOW);
     digitalWrite(Gin, LOW);
     delay(2000);
     digitalWrite(Gin, HIGH);
     digitalWrite(Mixer, LOW);
     delay(2000);
     digitalWrite(Gin, HIGH);
     digitalWrite(Mixer, HIGH);
     digitalWrite(WorkingLed, LOW);
     digitalWrite(ReadyLed, HIGH);
     delay(1000);
     
     Clicked = !Clicked;
}
else {
    // turn both pumps off:
    digitalWrite(Gin, HIGH);
    digitalWrite(Mixer, HIGH);
  }}
