  1. Hi there, Basically what i need is for my site to not refresh every time i click one of the buttons. I have got as far as finding out that it requires AJAX but i don’t have a clue how to use it This is some of my code...it basically covers the main parts but if you need more then please ask... <html> <head> <script> $(function() { var tabs = $( "#tabs" ).tabs({collapsible: true, active:"flase"}); tabs.find( ".ui-tabs-nav" ).sortable({axis:"x", stop:function() {tabs.tabs( "refresh" );} }); }); $(function() { $( ".box" ).draggable({containment: "#restrictor", scroll: false, snap: true, opacity: 0.35, cancel: ".box-content" }); $( ".box" ).addClass( "ui-widget ui-widget-content ui-corner-all" ) .find( ".box-header" ) .addClass( "ui-widget-header ui-corner-all" ) .prepend( "<span class='ui-icon ui-icon-minusthick'></span>") .end() .find( ".box-content" ); $( ".box-header .ui-icon" ).click(function() { $( this ).toggleClass( "ui-icon-minusthick" ).toggleClass( "ui-icon-plusthick" ); $( this ).parents( ".box:first" ).find( ".box-content" ).toggle(); }); $( "#container" ).disableSelection(); }); $(function() { $( "input[type=submit], #Buttons, button" ) .button() .click(function( event ) { event.preventDefault(); }); }); setInterval(function() { $('#timeval').load('Home_Automation/Includes/time.php'); }, 1000); </script> </head> <body> <!------------------------Serial Port/Commands/Functions---------------------------> <?php if (isset($_GET['action'])) { require("Home_Automation/Includes/php_serial.class.php"); $serial = new phpSerial(); $serial->deviceSet("COM3"); exec('mode COM3 BAUD=96 PARITY=n DATA=8 STOP=1 xon=off octs=off rts=on'); $serial->deviceOpen(); if ($_GET['action'] == "on") { $serial->sendMessage("L"); $file = fopen("Home_Automation/Includes/lights.txt","w"); fwrite($file, "1"); fclose($file); } else if ($_GET['action'] == "off") { $serial->sendMessage("l"); $file = fopen("Home_Automation/Includes/lights.txt","w"); fwrite($file, "0"); fclose($file); } else if ($_GET['action'] == "unlock") { $serial->sendMessage("D"); $file = fopen("Home_Automation/Includes/doors.txt","w"); fwrite($file, "1"); fclose($file); } $serial->deviceClose(); } ?> <!--------------------------------Main Container-----------------------------------> <div id="restrictor" class="ui-widget-content"> <!--------------------------------Controll Switches--------------------------------> <!-------------------------------------Doors---------------------------------------> <div class="box"> <div class="box-header">Doors</div> <div class="box-content"> <a class="button" href="<?php echo $_SERVER['PHP_SELF'] . '?action=unlock' ?>">Unlock</a> <div id="PHP"> <?php $file = fopen("Home_Automation/Includes/doors.txt", "r") or exit("Unable to open file!"); if (fgetc($file)==1) echo "<img src=\"Home_Automation/Images/Door_Open.gif\" />"; else echo "<img src=\"Home_Automation/Images/Door_Closed.gif\" />"; fclose($file); ?> </div> <a class="button" href="<?php echo $_SERVER['PHP_SELF'] . '?action=lock' ?>">Lock</a> </div></div> </div> </html> It’s not really in order as i cut bits out but that covers the basic code... If someone could please show me some code snippets that i would need to include or something that would be great Thanks, Chris
  2. Ah i have found the culprit... i forgot that my front ports messed up a while back and won’t play sound or anything... so i plugged the Arduino in the back main motherboard ports and now it’s all working!!! I done this before but it didn’t work so obviously it had something to do with the code as well Thanks for all the help and suggestions though! They were much appreciated Thanks a Bunch, Chris
  3. Right i think i got what you meant... My code now looks like this... <?php //check the GET action var to see if an action is to be performed if (isset($_GET['action'])) { //Action required //Load the serial port class require("php_serial.class.php"); //Initialize the class $serial = new phpSerial(); //Specify the serial port to use... in this case COM1 $serial->deviceSet("COM3"); exec('mode COM3 BAUD=96 PARITY=n DATA=8 STOP=1 xon=off octs=off rts=on'); //Now we "open" the serial port so we can write to it $serial->deviceOpen(); //Issue the appropriate command according to the serial relay board documentation if ($_GET['action'] == "on") { $serial->sendMessage("L"); $file = fopen("lights.txt","w"); fwrite($file, "1"); fclose($file); } else if ($_GET['action'] == "off") { $serial->sendMessage("l"); $file = fopen("lights.txt","w"); fwrite($file, "0"); fclose($file); But im still not getting anything. My arduino keeps resetting when i click the button to turn the LED on
  4. I don’t believe that the /r/n will change anything... i tried it and had no results. I also do think that they have something to do with the flush and line breaks or something along those lines. Thanks for the suggestion though
  5. Yea just checked and in the PHP code i sent before it says its sending an 'N' but i have changed that to an 'L'. So the Codes both match. Just to clear that up they were matching in the start so nothing has changed. Its still not working properly...
  6. Im not sure requinix :/ And kicken i think it is the PHP code not sending it corectly but here is the arduino code... int ldr = 0; int led = 11; int in = 0; void setup() { pinMode(led, OUTPUT); pinMode(ldr, INPUT); Serial.begin(9600); } void loop() { if (Serial.available() > 0) { in = Serial.read(); } if (in == 'L') { int val = (analogRead(ldr)); val = constrain(val, 150, 500); int LightLvl = map(val, 150, 500, 255, 0); analogWrite(led, LightLvl); } else (analogWrite(led, LOW)); I think i might have changed the if (in == 'L') part from the code i sent before but it matches on the PHP and Arduino code still.
  7. The linked 'ON' button from... <a href="<?php echo $_SERVER['PHP_SELF'] . '?action=on' ?>">ON</a> Do you see anything wrong with any of the code? I am using all of the code to communicate through my COM7 port to my Arduino. The bud rate and everything is correct and my Arduino 'RX' Light flashes when i Click 'ON' which means that it is receiving some kind of response. I am 100% sure that the code on the Arduino is correct so it must be to do with the PHP somewhere...
  8. yea it definitly works :/ when i click to turn the light on the arduino responds and the lights blink on and then off but they are supposed to stay on :/ could it be something to do with the flush or something?
  9. yea something similar... Here is the full code... <html><head> <style type="text/css"> body {background:white; color:black;} a:link {color:black;} /* unvisited link */ a:visited {color:black;} /* visited link */ a:hover {color:#00FF00;} /* mouse over link */ a:active {color:#FF0000;} /* selected link */ table.center { margin-left:auto; margin-right:auto; font-size:28 pt; } </style> </head> <body> <?php //check the GET action var to see if an action is to be performed if (isset($_GET['action'])) { //Action required //Load the serial port class require("php_serial.class.php"); //Initialize the class $serial = new phpSerial(); //Specify the serial port to use... in this case COM1 $serial->deviceSet("COM7"); //Set the serial port parameters. The documentation says 9600 8-N-1, so $serial->confBaudRate(9600); //Baud rate: 9600 $serial->confParity("none"); //Parity (this is the "N" in "8-N-1") $serial->confCharacterLength(; //Character length (this is the "8" in "8-N-1") $serial->confStopBits(1); //Stop bits (this is the "1" in "8-N-1") $serial->confFlowControl("none"); //Device does not support flow control of any kind, so set it to none. //Now we "open" the serial port so we can write to it $serial->deviceOpen(); //Issue the appropriate command according to the serial relay board documentation if ($_GET['action'] == "on") { //to turn relay number 1 on, we issue the command $serial->sendMessage("N\r\n"); //$serial->sendMessage("N1\r"); $file = fopen("testFile.txt","w"); fwrite($file, "1"); fclose($file); } else if ($_GET['action'] == "off") { //to turn relay number 1 off, we issue this command $serial->sendMessage("0\r\n"); //$serial->sendMessage("F1\r"); $file = fopen("testFile.txt","w"); fwrite($file, "0"); fclose($file); } //We're done, so close the serial port again $serial->deviceClose(); } ?> <table border="1" class="center"> <tr> <th>Lights</th> <tr> <td> <pre> <a href="<?php echo $_SERVER['PHP_SELF'] .

  10. Hey im new to this forum and to php. im look for some help as i cant seem to get my lights to light up on my Arduino Uno board using 'Serial Comunication' This is my code on the server... $serial->deviceOpen(); if ($_GET['action'] == "on") { $serial->sendMessage("N\r\n"); $file = fopen("testFile.txt","w"); fwrite($file, "1"); fclose($file); } else if ($_GET['action'] == "off") { $serial->sendMessage("0\r\n"); $file = fopen("testFile.txt","w"); fwrite($file, "0"); fclose($file); } And my code on the Arduino is listening to the serial port and is waiting for N. I know this is correct as i can test it by manually sending it an N... If you know what is wrong with my code please help me and if you need more code snippets then i will gladly post them. Thanks! Chris
