| can you explain how the actual connection in the power module was done from the controller board. i f possible also provide us the blueprint of the PCBs that you have made. |

The connection to the power module is not from the controller board,
the connection is from the controller to the LED PCBs, that's where the dimming / switching takes place. |

ah! that prices dropped very much, I think aurdi is costing 800appx.
now PCF8574 is something new to me let me checkout, I thought simple cascading was just fine.
I think someday I should post my mini too  |

hey sai i think arduino uno still costs around 1350 or so... there are so many indian versions of that available at lower prices.. and i think that also is enough, and compatible.
As madan said, the entire circuit for the LEDs is on the LED panel, from the controller only control wires goto the panel.
I already have the circuits pcb on this post, i think so. |

| Sushant, check out the earlier posts - 2 years old, the control circuit is posted there. |

I don't have the circuit as such but have the PCB image if u can get the info from that.
The basic is I use an Ethernet Cable to connect the controller to the power
Module instead of the DB cable as Before
The inputs from the controller - digital outs, are given directly to a ULN2004 and the output of te ULN is give to the control coil of the relays - a regular relay circuit with reverse diode tas indicated in the Arduino forums. You can check that out for more details.
Will see if I can add an image of the PCB shortly |

i was never good at writing a programme, so can you send me the sketch/codes for the same. |

Sushant, you'll not get the code, no one will give it to you, you need to develop it yourself or buy the coded product !
DIY or semi DIY ! |

Maaaaaan! these gadgets are super heavy to look, so much to just not use our good old "LIMBS"?
I'd still prefer my index finger to switch it on and switch it off. |

No code buys, just download the latest Aurdino gcc, and you ll get all your sketches. Its hell of a big forum for that card size equipment and you should get all your help there.
If ever you had arranged your friend list in orkut/fb, this sketch manipulations would be as simple. Hardware you now anyway know.
Still, I think PK did share it somewhere, cant be sure. |

Hi PK,
Just wanted to check with you if these relay will be help ful

It depends on the load that you are planning to connect. Every relay has a rating on the max load that you can connect to the relay. Hence it would be difficult to tell whether the above relay board would work for your situation.
If you are planning to connect only a power head, filter etc, then the above relay board would be fine. But if you are planning to connect a chiller, heater, you will have to go for a higher rating relay board. |

Imran these relays can take upto 6 A each.
If you connect to 220 V AC, that is 1320 watts per relay resistive load.
So you can easily do 500 watts or so. But be careful, these realys are notorious
for bad quality. They will simply get stuck in the ON position. I have used them and regretted it. |
