FINAL PROJECT: Phase 3

For Phase 3 I made a 3D modeling the vessel to hold the light. It will be a 2 tier structure in the general shape of a ladybug. I will use the photoresistors as the antennae of the bug so they can be visible yet remain unaffected by the glow of the LED. The LED will be underneath a shield shaped like a ladybug, with holes like a ladybug's spots for the light to shine through.  I will complete this AND will work on building the capacitance switch during this week. Printing the ladybug and assembling will be the final step in completing the project, which will be stage 4. Here is a rough sketch:


3D Model:


In terms of hardware, I've created the capacitance switch and linked it to the "buzzing" sound to imitate a sort of "purr". Here is a video of it in action:


And here is the code: (It may change by next week but this is mostly finalized)


#include <MedianFilter.h>
#include <CapacitiveSensor.h>

MedianFilter test(20,0);

CapacitiveSensor capSensor = CapacitiveSensor(4,2);

int threshold = 50;
bool pass = false;

int ledPin = 13;
int photocellInput = 0;
int soundPin = 9; 

void setup()  {
  Serial.begin(9600);
  pinMode(ledPin, OUTPUT);
  pinMode(soundPin, OUTPUT);
}
 
 
void loop()  {
photocellInput = map(analogRead(0),0,1023,0,254); 
     if(photocellInput < 30){
      digitalWrite(ledPin, HIGH);
      }
      else {
      digitalWrite(ledPin, LOW);
      }

      
 long sensorValue = 
  capSensor.capacitiveSensor(30);
  test.in(sensorValue);
  sensorValue = test.out();

Serial.println(sensorValue);

if (sensorValue > threshold)
  {
    if( pass == false) {
      pass = true;
      tone(soundPin, 20);
    }
  }
else {
      pass = false;
      noTone(soundPin);
    }
  
 
      

delay(10); //reading delay 
}

PROJECT 1 (2.0!) : LOCK BOX (For 3/26/19)

Image
I expanded upon my original idea to create the LOCK BOX. The goal is for the user to figure out the button path they must take in order to enter the correct password. Then the box opens for a surprise! The trick to this box, however, is that the button paths change after each successful box open. I have coded a total of 16 button paths, where one is chosen randomly after each successful open. The code allows the user to continue playing in a loop, and the trick to the challenge is a good memory. Here is a video of me playing with LOCK BOX: Here are some pictures: Here is the very long code for LOCK BOX: #include <Servo.h> Servo myservo; const int led1 = 8; const int led2 = 9; const int led3 = 10; const int led4 = 11; const int but1 = 6; const int but2 = 2; const int but3 = 3; const int but4 = 4; int randchoice; int butt1 = 0;        int butt2 = 0; int butt3 = 0; int butt4 = 0; int lbutt1 = 0; int lbutt2=0; int lbutt3=0; ...

Project one observations

 Project One Observations The main observation about my project is that it is difficult to get people to use LOCKBOX in the first place. The aesthetics of my design suffered due to time constraints and limited access to resources. A lot of people glaze over my project and walk away. It is incredibly difficult to create a design that people want to use for a variety of reasons. First of all, Working with a 6 and a half inch long breadboard makes it difficult to slim down down the size of my device. Second of all, plug in wires is not useful for the fact that they will fall out if not placed correctly. They also stick up a couple of inches, so this also creates size constraints. Third, the Arduino itself is finicky, has to be powered through the wall or my laptop, because I do not have the parts to convert to a 9V battery. To make it worse, the servo has to be placed at the opening of the box, so it is virtually impossible to hide. If you hide the servo, the box wouldn’t be abl...
