Interface and application programming

In this assignment we are going to use multiple interfaces to communicate with a device to perform an action on a pheripheral connected to it. We are going to use processing and MIT app inventor to create interfaces that communicate and control a peripheral on the device.

Processing

We implemented a simple processing interface that has a button in it. When the button is clicked, it sends a message on the serial port to the device telling it to change the state of the LED.

MIT app inventor

We implemented a simple mobile app that connects to the device via bluetooth and communicates a command to change the state of the LED.

I used the Board that I used in the output Week So If you want the board just back to week 13

I will Bring the Programmer And upload the Following Code

                                    

#include < SoftwareSerial.h>
SoftwareSerial mySerial(2, 1); // RX, TX

#define white 8
#define red 7
#define green 3
#define blue 0

unsigned int incomingData;
unsigned int incomingData1;
unsigned int incomingDataRAW;
int whiteColorIntensity = 0;
int previousIncomingData;

void setup() {

  mySerial.begin(9600);

  pinMode(white, OUTPUT);
  pinMode(red, OUTPUT);
  pinMode(green, OUTPUT);
  pinMode(blue, OUTPUT);
}

void loop() {
  if (mySerial.available() >= 2 ) // receive number from bluetooth
  {

    incomingData = mySerial.read();
    incomingData1 = mySerial.read();
    incomingDataRAW = (incomingData1 * 256) + incomingData;

    if (incomingDataRAW > 4) {
      whiteColorIntensity = incomingDataRAW;
      incomingDataRAW = previousIncomingData;
    }
  }

  if (incomingDataRAW == 1) {
    previousIncomingData = incomingDataRAW;
    digitalWrite(red, HIGH);
    delay(500);
    digitalWrite(red, LOW);
    digitalWrite(green, HIGH);
    delay(500);
    digitalWrite(green, LOW);
    digitalWrite(blue, HIGH);
    delay(500);
    digitalWrite(blue, LOW);
    digitalWrite(white, HIGH);
    delay(500);
    digitalWrite(white, LOW);
    delay(1000);
  }
  else if (incomingDataRAW == 2) {
    previousIncomingData = incomingDataRAW;
    digitalWrite(red, HIGH);
    delay(100);
    digitalWrite(red, LOW);
    digitalWrite(green, HIGH);
    delay(100);
    digitalWrite(green, LOW);
    digitalWrite(blue, HIGH);
    delay(100);
    digitalWrite(blue, LOW);
    digitalWrite(white, HIGH);
    delay(100);
    digitalWrite(white, LOW);
    delay(10);
  }
  else if (incomingDataRAW == 3) {
    previousIncomingData = incomingDataRAW;
    analogWrite(white, whiteColorIntensity);
  }
  else if (incomingDataRAW == 0) {
    digitalWrite(red, LOW);
    digitalWrite(green, LOW);
    digitalWrite(blue, LOW);
    digitalWrite(white, LOW);
  }
}


                                

MIT APP INVENTOR

I used to make Mobile Application Platform Called MIT APP INVENTOR

if you don't Know about app inventor Then I recommend to read this Documentation

First Let's Know about MIT APP interface

Let's see our Software interface How is Look Like ?

in the Left There are Layouts & Intrerfacing

Virtual Mobile In the Middle

Properties and Media In the Right

Here is the FlowChart of our Program

Let's know what the flow Chart is Telling us

The proram Consept is so Simple

Open the Program >>
Then It will apear the Blutooth Icon >>
Choose the Blutooth >>
If it Conncte Then Make the Following Orders
(if it doesn't Don't make any thing) >>
Choose the Modes You want to Add >> Do you want to Change the Mode (Yes/No) >>
Yes >>
Repeat the Cycle >>
No Contenue until You press off

---

So Let's Move on to the Blocks Codes

on the Left side we will find the Code-Blocks Menue

So Let's Make our Code and Begin to make the Software

So at Begining I will put Statment of the Bluetooth

For me I created 3 Difrrent Modes Every Mode Will be Responsible for Making Something

Mood one I will make It fading the Light Slowly and inter from colour to another in smooth way

Mood Two I will make it Fading the RGB light Too Fast and inter From colour to another in a sharp way

Mood three I will make it For white light and Control It's Brightness

Now what I'm Doing is to Build the Three Modes in App inventor, and Make Code for blutooth

Building the Condition of Mode 1

Builing the Condition of Mood 2

Building the Condition of Mood 3

After I finished From Coding I will Produce the Mobile App and Save it to my mobile

And now for the moment of truth

I downloaded the App on my smart phone and Programmed the PCB and we will see what will happen
