First stage of the coding ...

So today I got  code which would do morse code, when you type a message into the computer I found the coding from the book " 30 Auduino project for the evil genius". I typed the coding into the audino and it worked ! :) So i tried it out by typing  a message  and the LED light flashed the morse code.

Im thinking I want to use the LEDs and Pressure Pads to create a memory game. So there would be a series of  square Pressure Pads with LEDs, which would be set out in some sort of way. Each pressure pad would have a different colour LED built in. It will then show a pattern, where each pressure pad would light up at different times and the player would have to repear the pattern, by stepping onto the presssure pads and making them light up.

Morse Code

Morse code is a method of transmitting textual information as a series of on-off tones, lights or clicks that can directly be understand by other people.
Each character ( letter or number) is represented by a unique sequence of dots or dashes. the duration of the dash is three times the duration of a dot.
Morse code is measures in words per minute or characters per minute. The characters has different lengths because they contain different amount of dots and dashes. So that means words have different lengths.



I would use the LEDs for morse code by changing the duration of the flash of the LEDs for each letter, instead of the sound there would be flashes

So because I'm looking at pressure sensors, Lucy game me her dance may which uses pressure sensors, so i cut it open and looked at how the pressure sensors is used in the dance mat. The use some kind of plastic they has the circuit inti and the form with holes inbetween It which is what separates them both. so when someone steps on the mat the circuits become complete.

what im thinking now ... ?

I'm think that my project is going to be a something that you use to communicate via footsteps. You will be talking without actually speaking. The language will be through the lights flashes.

Some of the ideas:
 Communication system / Semaphore
 Some thing based around the game "Hop Scotch"
 Morse Code - use timing , so the length of time the light stays on for, will communicate something.
 Braille

The Tecnology I need:
 Pressure sensors that triggers LED to light up and form a pattern.

Its kinda like Fifreflies, they have lights at the end of their body and they use it to communicate,

a simple way to make a pressure sensor

this is a simple way of making a pressure pad, but if i could take the way he makes it and try and make it work with an LED light .....?

I'm Thinking. . .

It make sense for the surface area for my foot tile to be in the center of the tile ,but when people walk on the pavement do they always walk in the center of each tile? ...  I want the LED light in my pressure sensor to be in the center also.

Pressure Sensors

I started to look at what pressure sensors there are, and by looking i can see there is quite a few, some that measure gas annd liquids, but the one i thoug woud be more suitable for my project would be the "Pressure Switch"

Pressure Switch-  this is a form of switch that makes electrial contect when pressure as reached to the input. This is used to provide on/off switching from a pneumatic or hydraulic source. the switch is could be designed for either pressure rise of pressure fail.

when looking pressure sensors I found this video and this is the kind of thing i want to do, but as a bigger scale.

ideas...

so after having our group discussion, im more happy with looking more into my idea of using pressure sensors. My idea of trying to light up the pavements when people walk on them is quite a big thing to be doing, and wouldnt be suitable for the amount of time we have on this project. So I want to see how I can scale my idea down, so which it will be possable to have a good out come by the end of the project..... I could maybe produce a pressure pad of a smaller size, so it would do the same thing as the pavement would do just that it would be a smaller version of it.

ideas..

I dont have a clear idea yet, im still trying to figure what I want to do. After looking at "the fun theory" I want to do something that will motive people to do something right and have fun doing it.
..... like the video about getting people to walk up the stairs instead of taking the escalator... i want to et people to walk instead of taking public transport, so having a light up pavements, so when you walk along the road each pave stone you walk on shows a bring light...something around pressure sensors...?

....something that annoys people...something to do with smells, (people dont like horribles smells)...everyone smells differently ...??

... bad habits, stop people having bad habits....??

When you cover the sensor the light dims.
 the code for this ;


int analogPin = 0;    
                     
int val = 0;          

void setup()
{
  Serial.begin(9600);
  pinMode(11, OUTPUT);
}

void loop()
{
  val = analogRead(analogPin);  
  analogWrite(11, val / 4);
 
 
 
  Serial.println(val);          
}

Outline on things on the program Arduino

Arduino was written on Java. Java is a programe language designed to be used on many different computer systems.
when the programe recognizes the word is goes orange.


Function
A function is a block code, so when the function is called it runs. When Arduino is set up it look for a function. It will run the code inside the curly brackets. }

Verify- (play button). when you have done your code and then press verify if the writing goes white it means its ok and if the writing goes orange, then something has gone wrong.if the code is wrong them sometime it will highlight what part of the code is wrong.

To set up your Arduino - Tools and select which board you have.

Serial Port is there so you know your code has worked.

GND- Ground

HIGH = ON
LOW = OFF

There is always 3 wire that goes into a Arduino
    1 for the Ground
    1 for the values
    1 for the sensor

'Delay'- makes the programe stops ( makes it goes slower)
To slow voltage down you put in a resistor.

What is a variable ?

'int" is a number. stands for intriguer (whole number)
You give the number a name. (holder for the number) e.g 'analog pin' then you say what the number is = to. (analog number on the arduino)
because you have the number if you have to change the anlog number at anytime you only have to change it once, because you have named it.
When you make a variable you say what variable type by naming it then can use it in the way it is ment to be used.

Val- the number of the value of the sensor.
// -  then this sign is shown on the code, it just means that you can write a comment for people can read but the computer doest read it.

Analog

Analog is in between on and off. (0-1024) it takes all the different readings from light to dark.
All the colours are numbered
                  Dark- 0
                  White- 255
                  Middle-128
On an Arduino the sensor can sense a numer between 0 -1024
