| ==In-Depth: Smart Containers==
| |
|
| |
|
| ===Concept===
| |
| Question: Is there enough flour and sugar at home to make a cake for your friend's birthday tomorrow? Or do you need to stop at the store on your way home?
| |
|
| |
| Solution: Smart containers for your pantry — this way all you need to do is check your mobile device and you can see exactly how much flour and sugar you have at home. No need for unnecessary purchases or stops on the way home.

| =====Arduino=====
| |

| |
| int value; // value coming from the sensor
| |
|
| |
| void setup() {

| |
| 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 q; // example

|
| |
| void draw(){

| |
| }
| |
| 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
