Sure mate, sales@reanimate.com.au

Only just noticed that the picture didn't attach, but either way it turns out I fried my pin6 so I'm moved to pin 8 and changed the code to get it working which it now does. So all sweet. I think I'll worry about adding the RFID codes into the code manually later down the track. Out to buy a doorstrike now.

Hi Paul,

I came across an old post of yours from a while back which might help however, my code is a little more complex to start with the void loop and void writechip. Do I need to remove more of the if / else statements from my above code to implement.

Code:

int validSiteCodes[] = {196, 452};
int validSerialNumbers[] = {15809, 3285};

Code:

boolean IsTagValid(int siteCode, int serialNumber)
{
   boolean valid = false;

   // Determine how many valid tags there are
   int validTagCount = sizeof(validSiteCodes)/sizeof(int);

   // Loop through the arrays to see if siteCode
   // and serialNumber are present

   for(int t=0; t<validTagCount; t++)
   {
      if(validSiteCode[t] == siteCode &&
         validSerialNumber == serialNumber)
      {
          valid = true;
          break;
      }
   }
 
   return valid;
}

Code:

if(IsTagValid(siteCode, serialNumber)
{
   // Open the door. It's cold out here!
}

Well my Serial gives out usually correct information, this is from this morning:

All recorded Chips Erased! (Took three resets while holding pin6 low, after the fourth time and 30 second it registered)
All recorded Chips Erased!
Added Tag : 244A2B7 (Again had to reset a few times before the reader would see the card)
244A2B7
Matched Tag: 0 Access Granted (Took another board reset until the reader grabbed the id and about 10 seconds)

I am currently using a HID MiniProx but I have swapped the reader out with a new one and still no difference. The only thing I stupidly did was while building my button for pin6 (see attached pic) I shorted 5v to a Pin, so I'm wondering if I may have possibly buggered pin6, will run a simple code now to find out if its reading and outputting okay.

Sorry about the lack of info off the first post, end of a 19 hour day, brain wasn't working

Hello again, yet another thing I am working on is RFID for my door and am using the current code. However while it does run, it is very buggy when adding and removing cards for some reason, can anyone see an easy fix to remove the button sections and just manually add my RFID code 244A2B7 directly to the code?

Code:

//32 = bitwise 100000 - Set an initial mask to keep all tags 4 bytes long. WG26 (bits) plus another 6 = 32 bits or 4 bytes.

Hi Paul,

My PHP is certainly limited, but of C, Python, Processing etc I'm thinking its the quickest for me to continue with. For now my server is running win7, but I have a few machines I have lying around I can turn in linux boxes. As for relays, they will be controlling light rails, appliances and Solenoids.

The {} was just an example to break it up so its easier to read here. I knew I should have clarified that one when writing!!

The idea of the sensors attached to the controller is so the database has info on every room, I can then work on getting the server to trigger the relays depending on certain actions, ie dont turn off the lights when PIR detects movement. Turn on fan if over 30c etc etc.

Hope this helps to clarify. I currently have an arduino flicking of several relays around my house, but its a messy setup and I currently trigger my lights with 192.168.1.1/?2=on etc

Hello all,

I have been racking my brains for the 'best' solution to my problem but each has its merits and disadvantages. I am developing a home automation system for my home and would like to get some feedback, so anyway, here I go. (This is my rough idea)

As per the picture I want to have a 'control' module in each doorway which consists of:
- Etherten utilizing POE and ethernet for communications
- Temp Sensor
- Photocell
- 4 sets of on/off buttons (8 buttons total)
- PIR
- RGB Status LED

1. These modules will grab the pin status on a button press, PIR movement and every 30 seconds (for light and temp measurements) this is then pumps through to the server onto a database in a string format
{Controller-ID}{1:off,2:on,3:off,4:off,}{PIR:LOW}{LIGHT:643}{TEMP:32}

2. The server accepts data and checks to see if database holds the same values, if not update db and turn on relevant relays via secondary arduino, then send confirmation message back to original controler which flashes status ok LED.

I only have limited php experience so this is going to be a tricky one, any idea's of practical ways to do this would be appreciated as there is so many options.

Howdy Marque,

Any idea why my other pins are high? I can pop a led into any of my unused pins and the led lights up?

Very soon I'm going to buy another etherten and use the first one as a lightswitch that will send the status of the pins through to another etherten connected to my server. Server will use php to write values to a db, then switch relays accordlingly. As I'm not the best coder its a daunting task!

Hi guys,

I am using a bit of modified code, but for the life of me I cannot work out why all my pins are set to high, pins 2,3,4 start off as usual, but I can poke a LED into any other and its on Any ideas?

Hi Marque,

Wonderful combo you have written here, has become very handy to me. I would love to know how you went about coding the android part. Anyway I showed my code mods and what not here http://arduino.cc/forum/index.php/topic,132021.0.html

I'd like to control my relay setup with buttons also, would you have any tips for integrating this?

Thank you again!

Hi guys,

Been a while since I posted but I thought I would throw this up. I started off last night with Marque's excellent little script to allow for android, then built a little site for iPad access. As I am in a rented house this is all done with modified GPO's and old wireless double plug housings (see pic). Anyhoo, Once I move into my own house and tear the walls out the wiring will be a bit neater, but until then...

I've thrown the site mockup online @ www.reanimate.com.au/domotic/index.html (will need to sexify this with something nice and pretty)

Finally on the scheduling page I need to figure out how to get that working with php, cron and a flatfile, record the time and relay down and then open the url when the time is now. But a lack of php is causing a few headaches.

Code:

Hi Guys,

Been working for a few weeks on a project to turn on/off some power points via relays and using the EtherTen's ethernet features, so to start with I started with a basic bit of code to start a webserver on the arduino with a simple bit of text to click on and off the lights. However I didn't want to use the actual arduino hosted page due to its not so pretty looks, so I hosted a website on my XAMPP server that looks a bit nice and created a link to the arduino ie 192.168.2.102:84/?on1. The problem was that it navigated away from my pretty page and after three days I couldn't get an iframe to work so I have to use Jquery and JSON, see code below.

The XAMPP side code

Code:

The questions are...

1. Is there a way to for me to read the state of the relay (its not double pole so it would have to remember if its on or off) and request the information from my XAMPP site so when I go the page it can tell me if my lights are on?

2. I have a PIR that I would like to activate one of the relays by motion sensing as well as by my website? Ie I have a light outside plugged into one of the powerpoints with a relay and I would like it to turn on when I walk past. As well as being able to manually turn in on?

I can run a mysql database and php off my server to hold values if there is a way for the arduino to read commands from a database. That way the DB could remember the relay state.

Idea's and thoughts would be much appreciated.

Hi dc42,

Managed to figure out the Temp Action a little while ago before checking! but that snippet of code below is wonderous! Only thing is every fifth cycle while reading the sensor the LED pauses for 1 second. But that is no fuss to me! A while ago I came across someone doing a similar project and harvested the code for later keeping. I tried to implement this myself however when I checked the DateTime library it has been superseded! Would you by chance know how I could go about converting it? It's not much use if the lights are on all night!

Code:

#include <DateTime.h>

int lightSensor = 1;

int lightSwitch = 8;

int light_val;

//decide how many hours of light your plants should get daily
float hours_light_daily_desired = 14;

//calculate desired hours of light total and supplemental daily based on above values
float proportion_to_light = hours_light_daily_desired / 24;
float seconds_light = 0;
float proportion_lit;

//setup a variable to store seconds since arduino switched on
float start_time;
float seconds_elapsed;
float seconds_elapsed_total;
float seconds_for_this_cycle;

void setup() {
//open serial port
Serial.begin(9600);

//establish start time
start_time = DateTime.now();
seconds_elapsed_total = 0;

}
void loop() {
// read the value from the photosensor, print it to screen, and wait a second
light_val = analogRead(lightSensor);
Serial.print("light sensor reads ");
Serial.println( light_val );
delay(1000);
Serial.print("seconds total = ");
Serial.println( seconds_elapsed_total );
delay(1000);
Serial.print("seconds lit = ");
Serial.println( seconds_light);
delay(1000);
Serial.print("proportion desired = ");
Serial.println( proportion_to_light);
delay(1000);
Serial.print("proportion achieved = ");
Serial.println( proportion_lit);
delay(1000);

//update time, and increment seconds_light if the lights are on
seconds_for_this_cycle = DateTime.now() - seconds_elapsed_total;
seconds_elapsed_total = DateTime.now() - start_time;
if (light_val > 900)
{
seconds_light = seconds_light + seconds_for_this_cycle;
}

//cloudy days that get sunny again: turn lights back off if light_val exceeds 900. this works b/c the supplemental lights aren't as bright as the sun:)
if (light_val > 900)
{
digitalWrite (lightSwitch, LOW);
}

//turn off lights if proportion_lit>proportion_to_light, and then wait 5 minutes
if (proportion_lit > proportion_to_light)
{
digitalWrite (lightSwitch, LOW);
delay (300000);
}

//figure out what proportion of time lights have been on
proportion_lit = seconds_light/seconds_elapsed_total;

//turn lights on if light_val is less than 900 and plants have light for less than desired proportion of time, then wait 10 seconds
if (light_val < 900 and proportion_lit < proportion_to_light)
{
digitalWrite(lightSwitch, HIGH);
delay(10000);
}


}

Any suggestions for improvements or extra features in code/design please say!

Is it possible to have the code do two things at once? ie, can I have a green LED always blinking, and still run this code? I can't seem to find a way to program that without it doing the flash on and off, running the code (checking sensors which takes three seconds) then blinks on and off again!
