## What's IoT ?

[The Internet of things (IoT)](https://en.wikipedia.org/wiki/Internet_of_things) is the extension of Internet connectivity into physical devices and everyday objects. Embedded with electronics, Internet connectivity, and other forms of hardware (such as sensors), these devices can communicate and interact with others over the Internet, and they can be remotely monitored and controlled.

# FROM TRASH TO IOT


## CHALLENGE

**Re-Design, Re-Program and Re-conect any object into a IoT Object**

## OBJECTIVE

The objective of this learning activity is to involve students in the manufacturing process of a IoT (internet of Things) prototype, so that they get a general look at these technologies of manufacturing, and mainly understand the technical possibilities that each one provides, what materials can be used, the design processes and associated times.

## STEPS

### UNDERSTAND THE ELECTRONICS

**1. Identify all electronic components and note what they are (10').**

**HOW:** Use Google, ask your partner or ask your facilitator. ( in that order :-) )
*Some Keywords: resistor, breadboard, led, ldr sensor, moisture sensor, button, Nodemcu,jumpers, Arduino IDE*

**2. Connect all the components and test if it works (10')**

**HOW:** Use as a reference the schematic to connect all the components. Ask us if you have questions. ( See IoT Kits below )


**3. What does it do ?**

**HOW:** Describe in one sentence how it works/what it does.

### IDEATION

**1. Find in the lab materials / objects that can help you to create your IoT prototype(5')**
Some ideas: flower pot, boxes, cardboard, wood....


**2. Jam Session (25')**
Imagine 5 applications/ideas of IoT product depending of your electronics.
Some ideas: warning button, smart flower pot, light graph....

### PROTOTYPING

Split the group in two and:

**1. Create a IFTTT recipe (see IFTTT recipe section below) (30')**
Be cool! IFFT have a lot of services! ( Twitter, Mail, Drive, Telegram, Phone calls...)


**2. Re-design your object for assembling the electronics (30')**
You can use 3D printing ( take time! ) and/ or laser cutter. Ask us for help.

**HOW:** If you know Rhino use one of our computers. If not ask us!


### COMMUNICATION

Imagine you want to sell your IoT product to a possible business angel.

char password[] = "enteriaac2013";  // your network key

#define KEY "pz7QWW54kFi8y4mrbEMvkLjUEkRb3vr1RvN8n5JcWG5"  // Get it from this page https://ifttt.com/services/maker/settings
//#define EVENT_NAME "do_action1" // Name of your event name, set when you are creating the applet
#define EVENT_NAME "do_action3"

int led = 5;     // LED pin
int button = 4; // push button is connected
int temp = 0;    // temporary variable for reading the button pin status
IPAddress ip;
WiFiClientSecure client;
IFTTTMaker ifttt(KEY, client);

void setup() {
  pinMode(led, OUTPUT);   // declare LED as output
  pinMode(button, INPUT); // declare push button as input
  Serial.begin(115200);

  // Set WiFi to station mode and disconnect from an AP if it was Previously
  // connected
  WiFi.mode(WIFI_STA);
  WiFi.disconnect();
  delay(100);

  // Attempt to connect to Wifi network:
  Serial.print("Connecting Wifi: ");
  Serial.println(ssid);
  WiFi.begin(ssid, password);
  while (WiFi.status() != WL_CONNECTED) {
    Serial.print(".");
    delay(500);
  }
  Serial.println("");
  Serial.println("WiFi connected");
  Serial.println("IP address: ");
  ip = WiFi.localIP();
  Serial.println(ip);
  
}
void loop() {
  temp = digitalRead(button);
     
     if (temp == HIGH) {
        digitalWrite(led, HIGH);
        Serial.println("LED Turned ON");
         //triggerEvent takes an Event Name and then you can optional pass in up to 3 extra Strings
        if(ifttt.triggerEvent(EVENT_NAME,"Param1")){
          Serial.println("Successfully sent");
        } else
        {
          Serial.println("Failed!");

char password[] = "enteriaac2013";  // your network key


#define KEY "pz7QWW54kFi8y4mrbEMvkLjUEkRb3vr1RvN8n5JcWG5"  // Get it from this page https://ifttt.com/services/maker/settings
#define EVENT_NAME "do_action4"



int led = 2;     // LED pin D4
int temp = 0;    // temporary variable for reading the button pin status
IPAddress ip;
WiFiClientSecure client;
IFTTTMaker ifttt(KEY, client);

void setup() {

  pinMode(A0, INPUT);
  Serial.begin(115200);

  // Set WiFi to station mode and disconnect from an AP if it was Previously
  // connected
  WiFi.mode(WIFI_STA);
  WiFi.disconnect();
  delay(100);

  // Attempt to connect to Wifi network:
  Serial.print("Connecting Wifi: ");
  Serial.println(ssid);
  WiFi.begin(ssid, password);
  while (WiFi.status() != WL_CONNECTED) {
    Serial.print(".");
    delay(500);
  }
  Serial.println("");
  Serial.println("WiFi connected");
  Serial.println("IP address: ");
  ip = WiFi.localIP();
  Serial.println(ip);
  
}
void loop() {
   digitalWrite(led, LOW);
  int sensorValue = analogRead(A0);   // read the input on analog pin 0

  float voltage = sensorValue * (5.0 / 1023.0);   // Convert the analog reading (which goes from 0 - 1023) to a voltage (0 - 5V)
  Serial.println(voltage);

 
  if(ifttt.triggerEvent(EVENT_NAME,String(voltage))){
         digitalWrite(led, HIGH);

### Learning Experience in pictures


## OMNIA TRAVEL

### The Subject

Taking into consideration the interests of Omnia Travel, Fab Lab Barcelona proposes the development of a short immersive learning experience with the following features:
An immersive capsule where the participants will be able to experience **the cycle of materials** from the point of view of the FabCity concept, a new urban model of transforming and shaping cities that shifts how they source and use materials from **‘Products In Trash Out’ (PITO)** to **‘Data In Data Out’ (DIDO)**. This means that more production occurs inside the city, along with recycling materials and meeting local needs through local inventiveness.



### Objective
The objective of the activity is to involve participants in the manufacturing process of a **IoT (Internet Of Things) prototype**, so that they get a general look at these technologies of manufacturing, and mainly understand the technical possibilities that each one provides, what materials can be used, the design processes and associated times.
