My video

When it was all going so well and then ...

so as I went to go and film my video, I saw that all my arduino had been pulled apart, lucky that john was still at uni so he helped me get it working again but I could only get one lamp to work, so my video is not very good, but im gonna see what i can do in the editting which wont be very much :/

Coding for the second pressure pad

Its the same code which is used apart slight changes to the imput and output, i think this is right ?

// constants won't change. They're used here to
// set pin numbers:
const int buttonPin = 3;     // the number of the pushbutton pin
const int ledPin =  12;      // the number of the LED pin

// variables will change:
int buttonState = 0;         // variable for reading the pushbutton status

void setup() {
  // initialize the LED pin as an output:
  pinMode(3, OUTPUT);    
  // initialize the pushbutton pin as an input:
  pinMode(12, INPUT);  
}

void loop(){
  // read the state of the pushbutton value:
  buttonState = digitalRead(buttonPin);

  // check if the pushbutton is pressed.
  // if it is, the buttonState is HIGH:
  if (buttonState == HIGH) {  
    // turn LED on:  
    digitalWrite(ledPin, HIGH);
  }
  else {
    // turn LED off:
    digitalWrite(ledPin, LOW);
  }
}

Coding for my Pressure Pad

// constants won't change. They're used here to
// set pin numbers:
const int buttonPin = 2;     // the number of the pushbutton pin
const int ledPin =  13;      // the number of the LED pin

// variables will change:
int buttonState = 0;         // variable for reading the pushbutton status

void setup() {
  // initialize the LED pin as an output:
  pinMode(ledPin, OUTPUT);    
  // initialize the pushbutton pin as an input:
  pinMode(buttonPin, INPUT);    
}

void loop(){
  // read the state of the pushbutton value:
  buttonState = digitalRead(buttonPin);

  // check if the pushbutton is pressed.
  // if it is, the buttonState is HIGH:
  if (buttonState == HIGH) {    
    // turn LED on:  
    digitalWrite(ledPin, HIGH);
  }
  else {
    // turn LED off:
    digitalWrite(ledPin, LOW);
  }
}

Showing it works :)

Here is just a sort video of Tai trying out the Pressure sensor with the bulb lighting up, to make sure that it would work doing morse code.

Wiring up !

So here is where I wired up my arduino according to the one in my last picture, I followed and placed all the wires in the same place, and I added in my own pressure pad

I then wired it to an electrical box so I could use a proper light bulb instead of just a LED light.

After doing all the wiring and the coding, I tried it out to see if the light bulb would light up if I pressed down on the pressure pad.. . It worked !!

After making sure it all worked,I cut the wires down so it looked alot neater and you could see where the wired were actually placed.

wiring my arduino

So this is the wiring for whatIi had to put on to my arduino for my circet to work. I followed this picture for my own arduino

Equipment

My Pressure Pad

After making the mini pressure pad i made a bigger one but this time to make it more stable i used soft wood instead of cardboard, this way the pressure pad would keep its shape. I tried to make a bigger one with cardboard but after I stepped on it a few time it began to lose its shape. Now I have my pressure pad done i need to connect the wires to do and make the code to out into the arduino so the pressure works they way i want it to. Then I can communicate and send morse code using my pressure pad, and a LED light.

so I followed the video that i found on how to make a pressure pad, using just cardboard, tin foil, foam and tape. I made a small pressure pad but didn't have the wires to link it all up with an arduino, so that is my next stage to wire up the arduino and to make it work properly.
