Key codes – arrow key right left – text box value

admin — Sun, 06 May 2012 10:41:44 +0000

Created this snippet on one’s demands which refreshes my JavaScript knowledge.

Using this snippet you can increase focus cursor in textbox and place 1 or 2 value to text box on pressing left right arrow keys.

</p>
<p><script type="text/javascript"></p>
<p>function test() {</p>
<p>alert("Hiii");
document.getElementById("val").focus();
}
function fk(){
//document.getElementById("val").focus();
}</p>
<p>function kc(eve){
if(eve.keyCode == 37 ) { document.getElementById("val").value = 1; }
else if (eve.keyCode == 39 ) { document.getElementById("val").value = 2; }
}</p>
<p></script></p>
<p><body onload="test();"></p>
<input type="text" value="0" id="val" name="pri" onkeyup="kc(event);"/>
<p></code><br />

hope you all from google search will enjoy this post!



4 way Arduino traffic light
admin — Sat, 05 May 2012 05:24:55 +0000
Today i made 4 way Arduino traffic light. Its real world application with use of relay’s and high voltage bulbs as traffic lights. Here is the control circuit and sketch of this program.

Sketch : 
/*

4 way traffic light controller with red and green signals.

 */
int count = 0; 
void setup() {

  // initialize the digital pin as an output.

  // Pin 10, 11, 12, 13 has an LED connected on most Arduino boards:

  pinMode(9, OUTPUT);

  pinMode(10, OUTPUT);

  pinMode(11, OUTPUT);

  pinMode(12, OUTPUT);

  pinMode(13, OUTPUT); 
}
void loop() {
  if(count == 0) {

  digitalWrite(10, HIGH);

  digitalWrite(11, HIGH);

  digitalWrite(12, HIGH);

  digitalWrite(13, HIGH);

  delay(500); // blink led for first time on!

  digitalWrite(10, LOW);

  digitalWrite(11, LOW);

  digitalWrite(12, LOW);

  digitalWrite(13, LOW);

  delay(500); // blink led for first time on!

  digitalWrite(10, HIGH);

  digitalWrite(11, HIGH);

  digitalWrite(12, HIGH);

  digitalWrite(13, HIGH);

  delay(500); // blink led for first time on!

  digitalWrite(10, LOW);

  digitalWrite(11, LOW);

  digitalWrite(12, LOW);

  digitalWrite(13, LOW);

  delay(500); // blink led for first time on!

  digitalWrite(10, HIGH);

  digitalWrite(11, HIGH);

  digitalWrite(12, HIGH);

  digitalWrite(13, HIGH);

  delay(500); // blink led for first time on!

  digitalWrite(10, LOW);

  digitalWrite(11, LOW);

  digitalWrite(12, LOW);

  digitalWrite(13, LOW);

  delay(500); // blink led for first time on!

  digitalWrite(10, HIGH);

  digitalWrite(11, HIGH);

  digitalWrite(12, HIGH);

  digitalWrite(13, HIGH);

  delay(500); // blink led for first time on!

  digitalWrite(10, LOW);

  digitalWrite(11, LOW);

  digitalWrite(12, LOW);

  digitalWrite(13, LOW);

  delay(500); // blink led for first time on!

  count++;

}

  else { 
    // led 1
  digitalWrite(10, HIGH);

  digitalWrite(11, LOW);

  digitalWrite(12, LOW);

  digitalWrite(13, LOW);

  delay(10000); //
    // led 2
  digitalWrite(10, LOW);

  digitalWrite(11, HIGH);

  digitalWrite(12, LOW);

  digitalWrite(13, LOW);

  delay(10000); //
    // led 3
  digitalWrite(10, LOW);

  digitalWrite(11, LOW);

  digitalWrite(12, HIGH);

  digitalWrite(13, LOW);

  delay(10000); //
    // led 4
  digitalWrite(10, LOW);

  digitalWrite(11, LOW);

  digitalWrite(12, LOW);

  digitalWrite(13, HIGH);

  delay(10000); //
 } //  end of else statement. 
}
i have connected green LED’s to pin no. 10, 11, 12, 13 pin. where i am going to connect 3v or 5v relay. on NC point i am going to connect red light wire and on NO i am going to connect green ligh wires at high voltage side. 
Hope you guys will enjoy this project.

admin — Thu, 21 Jul 2011 17:33:01 +0000
Here is simple steps you can follow to move your wordpress blog without any 404 errors. 
we are explaining it in simple steps.

1) Goto your current host’s file manager and make zip of your domain. and using ftp download it on your hard drive.

2) Now goto myphp admin and take a backup of your current blogs database backup in sql zipped format on your hard drive.

3) Now log in to your hosting account and update your nameserver to new servers name server.

4) Now use ftp on new server, as most hosting accounts allows you to use some temporary ftp server till new name server takes time to use domain as ftp server.

5) upload downloaded zip to the folder where new site files locations allotted. (for this you have to add your domain to new server [ i.e addon domain section ] or add domain.

6) Then using new domains control panel create new database, user password now upload backup-ed sql database (step 2) to new database. Note down database name, username, password, host name ( some times its localhost. )

7) now using new servers file manager unzip your uploaded zip file in root of the domain and delete wp-config.php file.

8) Now wait till name server changes. they will take 1-2 hrs. some time less than than or more than this… then…

9) Navigate to your site you will get prompt to setup database. add all details. please note down your previous table prefix as in most cases its wp_ but some time where databases are limited you have to add prefix other than wp_ so note down from previous tables. and enter the same. prefix is to avoid over writing of tables while installing more than one  wordpress blogs on same database.

10)You done it.
