Dual clap switch. CLAP CLAP "ON" CLAP CLAP "OFF"

http://www.labviewarduino.in/2014/11/how-to-turn-on-ac-lights-and-fan-by.html

The above post which I explained How to turn on electrical appliances by clapping. Most of the Sound sensor which detect false trigger and makes the appliances to turn ON and OFF without clapping or start to work when there is other sound, Many people have complained about this and want to make the devices to turn On and Off for double clap. This post explains how to make a double clap switch. 

What are the components Need for this?

Arduino uno

Relay module (one relay module is enough) // I used 4 relay module because I don't have a single relay module with me.

Sound sensor

Make sure you are connecting the sound sensor to the 12th pin of arduino and Relay to 6th pin of arduino according to the program. This is the old circuit I used for the single clap switch. for double clap I've changed the program to use with 12th and 6th pin. 

IF you want to know how to connect circuit follow the video below to know .

download the arduino file from here

Whenever the sound sensor detects sound it produces 5v as output in this case it is a digital sound sensor. The sound sensor pin connected to the arduino. whenever the sensor activated it trigger the input pin of the arduino. when the input pin is triggered arduino starts to count the clap. Arduino will check for the next clap within 400ms . you can change this time limit to make it precise. whenever the count of the arduino equals 2 condition becomes true and it turn on the relay pin.

Wireless Virtual Switch Using LabVIEW and Arduino

Here's the example of using NI LabVIEW for controlling electrical devices wireless. I've used simple components to make this. I used  Arduino Uno, Relay module and RF Transmitter and Receiver. I've controlled only two devices, It can be extended upto  8 devices using RF Module which has 8 I/O's.

The above figure shows block diagram for the project.

Arduino Code for GSM Module basic program to find the network information

GSM Basic code to find the firmwire version, Network list, Network information, and baud rate. This uses the AT commands with the arduino command to communicate with the GSM module. I test these code with sim900a gsm module.

___________________________________________________________________________________

/*
Press--> a: AT Command.
f: To get Firmware Version.
l: To get List of Network.
i: To get Network Info.
v: To get VBAT voltage .
b: To get Baud rate Info.
*/

#include <SoftwareSerial.h>

SoftwareSerial mySerial(7, 8);

void setup()
{
  mySerial.begin(9600);               // the GPRS baud rate
  Serial.begin(9600);    // the GPRS baud rate
  delay(500);
}


void loop()
{
  if (Serial.available()>0)
   switch(Serial.read())
  {
    case 'a':
      AT();
      break;

void AT()
{
  mySerial.println("AT");

  mySerial.println("AT+CSQ");
  delay(1000);

  mySerial.println("AT+COPS?");

Select Actuator/Motor For your Machine design Using LabVIEW and SolidWorks

Here's the detail Video explanation about How to select motor for your New Machine design using Labview , SoftMotion and SolidWorks. 

Most of the Mechatronics or Mechanical Machines involves Motor to operate, in such cases it is difficult to select appropriate motor for the new design. Mostly motor selected after the Manufacturing of the Machine. 

LabVIEW and Solidworks collaborated to find a solution for this problem and come with a solution with the toolkit SoftMotion which collects data from Solidworks and interpret in LabVIEW with the data's collected from SolidWorks Its possible find the time to complete a task and able to find the appropriate torque that is required to move in certain axis. 

Download Labview Files from Here

Solidworks Assembly file can be find in the SoftMotion example Folder.

Temperature Control Using LabVIEW and Arduino

This is a very simple temperature control using LabVIEW and Arduino, where the user can set the minimum and maximum temperature if the temperature exceeds the maximum set level we can make the arduino to do certain work.

In this project I have set the arduino to turn On the fan when the temperature exceeds the set level. It is also possible to know the "HOT", "COLD" and MODERATE condition with the help of RGB LED and the front panel. 

Temperature log data are stored in a file where it can be later analysed the various temperature data respect to the time. 

What are the components used?

RGB LED

LM35 Temperature sensor

Arduino Uno.
