Final thoughts

Project 3 I can say was certainly a challenge. I had worked with circuits before but I still had very little experience in electronics and using arduino was new to me so trying to get my head around it in such little time was overwhelming. During my project I had my share of ups and downs, one of my down time was when I kept trying the ultrasonic motion detector and it repeatedly produced inconsistent results, in opposite to that one of my up lifting moments was when my circuit worked as planned because the infrared motion detectors were a success.  
I have found out some intriguing stuff regarding how cigarette butts are harmful to the environment also that they are in fact recyclable and butts can be used to prevent steel corrosion.
I have learnt a different way to approach future projects if it's relevant of course :) Arduino is a great bit of electronic and I am pleased it was introduced because I probably wouldn't have used it otherwise.
I am fairly satisfied with the outcome (The Baha Butt Bin) but fairly because I know there is always room for improvements :) The prototype was working and I can certainly see potential in it.
The presentation also went well although there was more I planned to say but didn't, oh well they do say short & sweet is good:)

Feedback
Juliet and John's query where both regarding what could be done differently... so if I was making the bin to be mass produced lets say :) what would I change about my prototype?...
So I'd change the material as its made from MDF wood I would perhaps used steel or aluminium, also the circuit would need to be housed so it's kept away from butts but most importantly any lit butts that aren't stubbed out properly.
John asked why I didn't use a heat sensor instead of a motion sensor because people could play around with it for the attraction if it's just a matter of detecting motion, however if I used a heat sensor heat would have to be applied to trigger the attraction. I didn't have a reason for not using heat sensor instead in fact I looked at heat sensors early in my project briefly so heat sensor would be a better idea for improving quality of use.
Also the wires in the circuit had a tendency to pop out which stopped the flow and irritated me so I taped them down with small bits of duck tape, however in the real world this wouldn't do and so Pete suggested the possibility of soldering to stop the wires popping out, this is therefore a process I could use in further development.

lol after a few attempts of shooting this scene, I decided I would pack up for the night but I wasn't entirely satisfied :) so I decided I would shoot another video to please ma self.

A Target Location

As you can see cigarette butts are being thrown on the ground in this area an awful lot, the littering of cigarette butts is what I want to try and reduce, therefore this could be a location for my potential butt bin.

The set up

Arduino Code:

/*

  AnalogReadSerial

 Reads an analog input on pin 0, prints the result to the serial monitor

 This example code is in the public domain.

 */

void setup() {

  Serial.begin(9600);

  pinMode(3, OUTPUT);

}

void loop() {

  int sensorA = analogRead(A0);

  int sensorB = analogRead(A1);

  int sensorC = analogRead(A2);

  if(sensorA < 600 || sensorB < 600 || sensorC < 600){

    digitalWrite(3, HIGH);

    delay(2000);

    digitalWrite(3, LOW);

  

  }

 Serial.println(sensorA);

    Serial.println(sensorB);

    Serial.println(sensorC);

    Serial.println(" ");

}

Remember this little guy that I cut open before I stitched him back up he’s almost as good as new. J

He's been connected to the circuited so when a cigarette butt is thrown into the but bin his job is to dance and sing.

I originally planned to add a casino jackpot sound to an audio device which would have been the sound to activate the above moving object however Juliet and others liked the song the toy already sang, so I was happy to go a long with using its original features, I reckon it seemed more fun than the casino jackpot sound anyway. 
To be honest I'm more pleased the circuit works. J

Brief Overview

I'll be using infrared motion detectors, resistors are typically added to reduce the flow of current in the circuit, an arduino board, a bred board, a sound activated object and a mosfet used to switch the current in the toy on/off.

Infrared Motion Detector / soldering

So Pete suggested I use infrared motion detectors now as they would work better for me. I  had to put a few of these together by soldering.

Easy once i got the hang of it J
