Power Flic

Overview

The basic idea is to turn on/off a physical button. Our experiment turns out to be using Arduino yun, flic to control a power strip.

Step 1: Material

• Arduino yun board
• Jumper wires
• Mini servo
• Power strip

Step 2: Set up Arduino with mini servo

Step 3: Connect with WiFi network

• Connect Arduino Yun with WiFi network
• Connect phone with the same network
• Open Flic app in the phone and set up click with HTTP request

Step 4: Write some code in Arduino

#include <Bridge.h>
#include <BridgeServer.h>
#include <BridgeClient.h>
#include <Servo.h>

// Listen to the default port 5555, the Yún webserver
// will forward there all the HTTP requests you send
BridgeServer server;
Servo myservo;
void setup() {
  // Bridge startup
  pinMode(13, OUTPUT);
  digitalWrite(13, LOW);
  Bridge.begin();
  digitalWrite(13, HIGH);


  // Listen for incoming connection only from localhost
  // (no one from the external network could connect)
  server.listenOnLocalhost();
  server.begin();
  myservo.attach(5);
}

void loop() {
  // Get clients coming from server
  BridgeClient client = server.accept();

  // There is a new client?
  if (client) {
    // Process request
    process(client);

    // Close connection and free resources.
    client.stop();
  }

  delay(50); // Poll every 50ms
}

void process(BridgeClient client) {
  // read the command
  String command = client.readStringUntil('/');

  // is "digital" command?
  if (command == "digital") {
    digitalCommand(client);
  }
}

void digitalCommand(BridgeClient client) {
  int pin, value;

  // Read pin number
  pin = client.parseInt();

  // If the next character is a '/' it means we have an URL
  // with a value like: "/digital/13/1"
  if (client.read() == '/') {
    value = client.parseInt();
    turnServo(value);
  } else {
    client.println("can not read value");
  }

  // Send feedback to client
  client.print(F("Pin D"));
  client.print(pin);
  client.print(F(" set to "));
  client.println(value);
}


void turnServo(int value) {
  //turn off is closewise
  if(value == 1) {
    myservo.write(180);
  } else {
    myservo.write(0);
  }
    delay(500);
    myservo.write(90);
    delay(500);
}

Step 5: Done and try out
