    Hi Guys,

    I recently got into arduinos and am really enjoying them and thought I'd share my first project with them.

    Its a used for controlling my Immersion switch. I can send it commands via Telegram to turn on or off the Immersion, and also a boost which will turn it on for an hour and then turn it off.

    • The chip is an Wemos d1 mini , its an arduino with built in wifi (Its $4 delivered from Aliexpress!). This connects to my wifi and communicates with Telegram (which is a IM client, very like whatsapp)
    • The orange thing is a servo motor that flicks the switch
    • The grey faceplate and switch extender are the black motor arm are 3d printed.

    This is what you see when you are messaging the bot:

    At the moment I'm powering it with a battery pack (I need to change it every 3 days or so) but will be changing to mains soon.
    The reason i need the extender is that the switch is very stiff and the motor wasn't strong enough to flick it, so I had to get some law of the lever going.
    I tried to use sugru to stick the extender to the switch, but it wasn't strong enough, so I ended up superguleing it.

    I've been using it for the last 2 weeks or so and its working out great! Really happy with it.

    I've a few more ideas in mind for it, such as been able to add a schedule (like turn on every morning at 7 or whatever)

    For more information on the code and parts you can check out the projects github page

    Nice project. I love the mechanical switch connection - i wouldn't have even thought of doing that, i'd be running the lot through a relay or something so interesting to see different approaches.

    Quite some time ago i made a heating controller with an android tablet that allowed you to program it via a google calendar. I don't go into any detail of the specifics of that bit on my blog but you can read a bit about it here: http://www.chet.ie/?p=178

    That controller has long been replaced and the code gone with it but if its something you'd like to do (and are on android) then i can dig into it.
