| ==In-Depth: Smart Containers==
| |
|
| |

| ===PDF Version===
| |
| [http://doubledi.com/indepth/jpgs/InDepth.pdf In-Depth: Smart Containers PDF]
| |
|
| |
| ===Concept===
| |
| These smart containers are a response to all the rotten food, unnecessary purchases, and special cravings you've ever had. Now you can see what's in your kitchen from where ever you are, just by checking your smart phone. <br>

| |
|
| |
| ===Product Function===
| |
| The final product would have a short-distance sensor and wifi chip embedded within the lid of the container. The wifi chip would auto FTP the food data levels by sending the data to the wireless local area network. This info could then be accessed remotely with any web-enabled device, by logging into a secure account. <br>

| =====Arduino=====
| |
| <source lang="java">
| |
| int sensePin = 1; // infrared sensor to analog pin
| |
| int value; // value coming from the sensor
| |
|
| |
| void setup() {

| |
| }
| |
|
| |
| void loop() {
| |
| int value = analogRead(sensePin); // current value of the sensor
| |
| byte scaledVal = map(value, 0, 600, 0, 255); // rescale to send as one byte
| |
| Serial.write(scaledVal); //print the distance
| |
| delay(100); // arbitrary wait time
| |
| }

| </source>
| |
|
| |
| =====Processing=====
| |
| <source lang="java">
| |
| Serial myPort; // variable for the serial
| |
| import processing.serial.*; // reads information coming in through the server via Arduino
| |
| int incomingVal; // incoming number value
| |
| int r; // example
| |
| int b; // example
| |
| int q; // example
| |
| int o; // example

|
| |
| void draw(){
| |
| background(0); // background black for visualization
| |
| while(myPort.available() > 0){
| |
| incomingVal = myPort.read(); // while new data coming in from Arduino, store in variable
| |
| }
| |
| float reVal =map(incomingVal, 51, 255, 0, 255); // rescale the incoming value to the depth of the container
| |
| fill(reVal); // fill the visualization with the rescaled incoming value
| |
| rect(0,height - reVal,width,height); // draws rectangle of the incoming value
| |
| println("Flour:" +(reVal)+ " Sugar:" + r+ " Oats:" + b+ " Pasta:" + q+ " Millet" + o ); // incoming value to be seen in console
| |
| PrintWriter output = createWriter("data/data.tsv"); // send info to external file
| |
| output.println("Flour:" +(reVal)+ " Sugar:" + r+ " Oats:" + b+ " Pasta:" + q+ " Millet:" + o ); // directs which information to be written to new file
| |
| output.flush(); // write the info
| |
| }

| </source>

| =====PHP=====
| |
| (Gets the data from an automatically uploaded file from desktop)
| |
| <source lang="php">
| |
| <?php
| |
| $file_handle = fopen("data.tsv", "r");
| |
| while (!feof($file_handle)) {

| |
| echo $line;
