Wall mounted 'mood light'
-
(there is a sketch for MySensors v2 available)
I received my 110v-230v AC to Mysensors PCB board last week en spent a few hours this weekend making 2 wall mounted mood lights.
I looks a little cheap from the backside but very luxurious on the wall ( < €20 total) and fully "MySensored".
I did not use the relais on the board (and discarded some of the safety measures
). Very basic: a cut WS2812b strip, a few wires.
Case is 12 mm MDF Board painted with Chalk paint (no primer needed, ready in half an hour ;-))Basic sketch with FastLED library (or Adafruit) with V_RBG.

Love your project and good use of the wall mount PCB. You showed me that I really need to order a couple of those I'm tired of all the phone charger cables
I couldn't really see it well on the photo's. But did you paint the back of light as well, the MDF part I mean? If not I would do it, because MDF has the tendency to bend when painted on one side only. That's why I use plywood or solid wood for almost all of my projects. Learned it the hard way, I made a cover for my radiator once out of MDF and painted only the outside. In just a day or two the cover started to bend. Which was really not funny after spending two weekends making it.
If you decide to paint the back side as well I'd use a white paint, that reflects the light coming from the ledstrip better. Other colors tend to absorp the light more.
I'm also really curious about how you mounted the MDF to the wall. It looks really great.
-
Could you please post your Arduino sketch, as I want to build something similar?
Thank you.
-
@TheoL Thank you for the tips. I painted the board on all sides. I would prefer real wood but MDF is really easy to model and I had a few sq meter left. I hate the dust though. For mounting i used a hook which fits in hole.
-
@gloob I will post the sketch after cleaning it up. I need to add on/off/ scene button functionality.
I allways try to make my nodes as autonomous as possible. That way i'm not fully controller dependent and it's more safe.

@AWI said:
...and discarded some of the safety measures
...I see you've got something soldered where the fuse should be, but for the rest I can't see what you've left out. Could you tell us which components you eventually ended up using? (or not using, whatever you prefer :))
-
@mvdarend I have not used the SSR, the varistors and the fuse on the low voltage side...

I have updated the sketch to allow for independent operation and added a few light effects. The sketch can be used for any "Neopixel" (WS2812(B)) LED strip/ stick/ circle. Uses V_RBG and/ or V_STATUS and separate actuators (or the push button with long push) to switch the Pattern and Alarm. A few examples:
"Alarm"
Wall Light fireplace – 00:06
— Ad Imhoff"Fireplace"
Wall Light Alarm – 00:04
— Ad Imhoff"Candle light" and "Rainbow" mostly non blocking code. If somebody want to add please do so.
The sketch, heavily commented. Can always be improved

hello,
i've problem with the sketch :+1 :sketch_dec08a.ino: In function 'void setup()': sketch_dec08a:89: error: 'S_INFO' was not declared in this scope gw.present(RGB_TextColorChild, S_INFO, "RGB Wall textcolor 0"); ^ sketch_dec08a.ino: In function 'void incomingMessage(const MyMessage&)': sketch_dec08a:308: error: 'V_TEXT' was not declared in this scope gw.request(RGB_TextColorChild, V_TEXT); ^ sketch_dec08a:313: error: 'V_TEXT' was not declared in this scope if (message.type == V_TEXT) { // if get color from text child ^ exit status 1 'S_INFO' was not declared in this scope

S_INFO inly exist in the dev branch.
That also means you have to convert the 1.5 sketch. Convert instructions here:
https://docs.google.com/document/d/1NKq5uuNdnxF5jWnum7VT32mbKLjuvqlx2A5D1qQ-H3Q/edit#
-
@mickaelr30 , did you ever get this working with 1.5?
i've got the upgrade instructions, but struggling to reverse it so it works with my current setup. Don't think i'm quite ready to upgrade all my nodes to dev quite yet.
-
@Adam-McCartney add these lines in the header and you will have it working with the production version...
// V_TEXT & V_INFO when not using the DEVELOPMENT version const byte V_TEXT = 47 ; // values taken from development edition MyMessage.h const byte S_INFO = 36 ;
-
@AWI said:
// V_TEXT & V_INFO when not using the DEVELOPMENT version
const byte V_TEXT = 47 ; // values taken from development edition MyMessage.h
const byte S_INFO = 36 ;awesome, thanks!
I'm more of a butcher than a surgeon. I can quite happily take things apart, but fixing things usually goes right over my head!!
-
I really love this project.
May I can include it in all of my sensors (doorbell, thermostat, alarm,...).Really sounds great, thanks
-
Is there a way to get your wiring schema ?
-
@Mehdi-HAMIDA There is nothing to it. A standard MySensors node (5v) with the strip connected to D5 and a button between ground and D4.
const int stripPin = 5 ; // pin where 2812 LED strip is connected const int buttonPin = 4 ; // push button
-
@AWI OK, just ordered the PCB
thx
-
@AWI: Won't this part of your sketch create sort of an endless loop?
case RGB_TextColorChild: // Text color from controller if (message.type == V_TEXT) { // if get color from text child gw.request(RGB_TextColorChild, V_TEXT);
-
@mfalkvidd Good observation. Probably the the result of an 'efficient' copy/paste
The line
gw.request(RGB_TextColorChild, V_TEXT);I there with no reason, can be deleted...
-
Im building the same light, but i use 12v LED strips controlled with mosfets. Is it possible to use the same scetch?
-
@Tore-André-Rosander If you use standard 12v strips it won't work as such. The ws2812/11 chips in the strip used make it possible to address the individual led's.
-
@AWI Is this code for version 1.5?
Im trying to compile it for the dev (v2) but i get a lot of errors.
Mostly alot of code that "was not declared in this scope".EDIT: Just found your link to the "Conversion guide", will have look at it!

A version for MySensors 2 is available at https://forum.mysensors.org/topic/4934/wall-mounted-mood-light-v2
