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.
