@frog thx a lot for your input and for the link! :) I agree there are lot of stuff available on the net that i have found but it’s not always clear for me as i don’t have any electronic background… and people here are very very helpful to explain and share info :) things like “can i use the 2x 5v pins at the same time?” or “how many things i can connect to the 1x 5v at same time?” those kind of question i didn’t find answers on the net… and i still don’t have lol so i thought i would ask here as it’s also a good playground

Hello! this post is not directly related to MM but can help to understand how to use the gpio pins on a RPI3. I have been playing around with MM since few months now and wanted to use the gpio pins a bit more for instance to integrate sensors etc. But my problem is the understanding of the gpio pins before plugging anything in a wrong way. If anybody want to share knowledge about how the pins works, things to consider, best practice etc, you are more then welcome :)
For a start I was asking myself why there are 2x (pin 2 and 4) 5V output when the Pi is only powered by 1x 5V? I assume both pins can be used independently? thx for any info :)

it’s solved ;-) thx anyway

hi @Beh ! unfortunately your module is not working for me :( could you please help me to figure out why? i have bought the same PIR sensor and plug it in the gpio 14 (physical pin 8) thx!

@Goldjunge_Chriz ok then i can’t order… my mirror size is less the 0.4m2. can you just tell me the % of the glass on the pics? (Lichttransmission)

@Goldjunge_Chriz thx for your offer! really cool. could you please let me know how much it would cost to send to swiss pls? thx

hi @mochman - i don’t really get what is the use of your module… could you please give me some use case pls? thx a lot

@alexyak Very nice job! it’s exactly what I had in mind when I open this topic. Sad that can’t be run on RPI…

hi @bhepler ! thx for sharing your findings!i will try this settings later this week. before to get into it, could you please let me know if it will also work without a RaspiCam?? usb camera is ok? where did you put/hide your own cam? thx :)

@alexyak which is your dev box if i may ask?
