Recitation 5: Leander’s Report

In today’s class, we made a workout circuit based on the tilt switch. We applied the instruction to building and tested the circuits to let them fit our demand situation. We try to use the special function of the tilt switch to count our movement. The process was separated into three different parts

Step 1: Detecting transition

we use the workout circuits to count the number of our movements. At the time we rolled the tilt switch, the program will detect it and plus one based on 1 for each time. IMG_0101

const int SENSOR_PIN = 6;  
  
int tiltVal;

void setup() {
  pinMode(SENSOR_PIN, INPUT);    // Set sensor pin as an INPUT pin
  Serial.begin(9600);
}

void loop() {
  // read the state of the sensor
  tiltVal = digitalRead(SENSOR_PIN);
  Serial.println(tiltVal);
  delay(10);
}

Step 2: Serial Plotter

We used the graph instead of the number in the serial monitor so that we can view the changes in the way we move the tilt sensor more obviously. 

const int SENSOR_PIN = 6;
int tiltVal;
int prevTiltVal;
void setup() {
 pinMode(SENSOR_PIN, INPUT);    // Set sensor pin as an INPUT pin
 Serial.begin(9600);
}

void loop() {
 // read the state of the sensor
 tiltVal = digitalRead(SENSOR_PIN);

 // if the tilt sensor value changed, print the new value
 if (tiltVal != prevTiltVal) {
   Serial.println(tiltVal);
 }
 prevTiltVal = tiltVal;

 // for Serial Plotter use
 //Serial.println(tiltVal);

 delay(10);
}

Step 3/4: Workout

 

const int buttonPin = 6; 
int buttonState;             // the current reading from the input pin
int lastButtonState;
int haha=0;
// the previous reading from the input pin

// the following variables are unsigned longs because the time, measured in
// milliseconds, will quickly become a bigger number than can be stored in an int.
unsigned long lastDebounceTime = 0;  // the last time the output pin was toggled
unsigned long debounceDelay = 0;    // the debounce time; increase if the output flickers

void setup() {
  pinMode(buttonPin, INPUT);
  Serial.begin(9600);
  Serial.println("Start your workout");
}

void loop() {


   debounceDelay=millis()-lastDebounceTime;
   
  // read the state of the switch into a local variable:
  int reading = digitalRead(buttonPin);
  
//  // If the switch changed, due to noise or pressing:
//  if (reading != lastButtonState) {
//    // reset the debouncing timer
//    lastDebounceTime = millis();
//  }
if (debounceDelay<=20000){
  if ( reading != buttonState) {
    // whatever the reading is at, it's been there for longer than the debounce
    // delay, so take it as the actual current state:
      buttonState = reading;
      haha++;
     Serial.print("You've down curls for ");
      Serial.print(haha);
      Serial.println(" times.");
  }
}
  else {
    lastDebounceTime=millis();
    Serial.println("Stop, your time is up!");
  }
  // save the reading. Next time through the loop, it'll be the lastButtonState:
  lastButtonState = reading;

 //if you want to use Serial Plotter, add these two lines:
  //Serial.println(buttonState);
  //delay(1);
}
