help please

Former Member

hi

 

i am looking to make a project but have no programming experiance at all.

 

if i give a brief description maybe someone can tell me if its possible or not.

 

 

i am trying to link across a network of a school to bring on a 230volt relay in various  locations.

 

i would like a year planner that i could set the times and dates to bring on the various relays.

 

 

is this possible?

if so what bits would i need?

 

as i say i have zero programming skills so if this is possible and someone would like to do the programming for me then please get in touch.

 

thanks andy

  • hi

    to clear things up.

    im an electrician with many years experiance, so i know what i want just dont have the programing skills to do it

     

    i need a relay that will switch 230v ampage is not important as it will be switching a controll circuit. so there will be no real load

     

    i want to use ethernet connection and work over a LAN.

     

    im after a program i can load up, select the days of the week on a year planner, and set a time on and off for the selected days.

     

    then store the info on the device and leave it running, e.g i do not want the pc plugged in all the time to keep it running.

     

    it would need to be able to store a whole years worth of info.

    so the operater would change setting once a year.

     

    If anyone has the skills to write a program to do what im after id be happy to pay for there time

     

    many thanks for your time

    Hi Andy,

     

    The relay part is easy (oomlout has a great example) and inexpensive.

     

    Turning it on based on a yearly schedule is relatively easy. I would guess storing day, hour, minute would be detail enough. Depending on how often you have an event, it may require more memory (ie, use the Arduino Mega instead of a nano or uno).

     

    To get that list of events onto the Arduino, you would like to use a LAN connection... that should also be fine.

     

    So what's left is some sort of PC based software that does all the scheduling, then creates a list, and allows it to be uploaded to the Arduino that controls the relay. This could be time consuming to build.

     

    The Arduino controller side is multiplied many times to allow LAN connection to one of dozens of different Arduino controller boards across the school. So each controller needs a unique identifier of some sort.

     

    I'd be interested on taking that on. Private message me if you'd like.

    But like others mentioned, it would likely be much cheaper or free if you found a local college or university to take it on as a project for one of their classes.

     

    Cheers,

    -Nico
