Ability to change color by physical button?
-
Yeah… I have no idea what the heck i am doing^^,
This is way over my league.
Is there any good beginner guides for me? :p
I have been looking thru the PIR-Sensor module (and other) whilst reading the “Module Dev. Docu.” trying to understand. -
https://www.raspberrypi.org/learning/physical-computing-with-python/ maybe this can help you to understand how the gpio pins work, but it’s a different programmin language as in this project
-
The python-button part is something i tried before, its the other language i have great difficulties with. (The one that MagicMirror is coded in.) since i dont understand The language, i cant read it and change/re-write what is needed for my idea to work. Ive been trying for 4h now.

if you post your code in here we may can assist you a little bit
-
I dont have any code. All this time i have been trying to understand what i am trying to do. If we look at The code from PIR-sensor, i dont know wich line are doing what. I have no clue on how and where to start. I cant see to understand The “building” of a module. All The “this. File” and what not dont make Any sense to me.
I need a How-to guide for toddlers :P -
i hope the following lines can help you to understand it a bit more and that it is explained correctly.
this references the module itself
so in the module you can do this.sendSocketNotification(…) which will call the function sendsocketnotification of your module (this)
also you can follow this guide to develop a module https://github.com/MichMich/MagicMirror/tree/master/modules
/* Magic Mirror * Module: MMM-PIR-Sensor * * By Paul-Vincent Roll http://paulvincentroll.com * MIT Licensed. */ /* registers a module with the name MMM-PIR-Sensor in the magic mirror system*/ Module.register('MMM-PIR-Sensor',{ /*config part*/ defaults: { sensorPIN: 22, /*number of pin can be different for raspberry pi version e.g. https://raspilab.files.wordpress.com/2014/08/gpiosb.png*/ relayPIN: false, /*this is for using relais in this module not needed because you can also set the hdmi output off*/ powerSaving: true, relayOnState: 1, /*not important because you're not using relays*/ }, /*here you receive messages which you send via node_helper.js*/ socketNotificationReceived: function(notification, payload) { if (notification === "USER_PRESENCE"){ /*when you receive the notification user_presence from your node_helper you send a global message with this notification to every module in magic mirror so they can handle this event as well*/ this.sendNotification(notification, payload) } }, /*this method got fired when the core is starting your module start: function() { /* the following 6 lines can be removed if you don't want to use relais.

i was to late to edit :pensive:

Thank you Strawberry with everything.
I think i have to give this idea up tho. I have now been sitting for two days trying. But i just cant wrap my head around it. :/
Nothing makes sense for me with JavaScript. Not a single row of code have i been able to write.
Changing ‘fontColor’ is about my level of knowledge :P -
maybe this will give you a start
I added the following lines to MagicMirror/css/custom.css
.male { background: black; color: blue; } .female { background: white; color: pink; }and for testing I edited the clock module (MagicMirror/modules/default/clock/clock.js) because it get’s updated every second.
put those lines right after line 69
if(secondsWrapper.innerHTML % 10 == 0){ /*changes class every 10 seconds, because i don't have a button i made this "hack" for testing purposes*/ var body = document.querySelector('body'); if(body.classList.contains("male")){ body.classList.remove("male"); body.classList.add("female"); } else { body.classList.remove("female"); body.classList.add("male"); } } -
Hi… This can easily be accomplished with some javascript and css. No need to mess with hardware or anything.Edit: I guess I should actually read the post. You need a physical button. Disregard lol
