Thanks to the help I've received on here the last few days I have been able to put together a schematic for a project I am planning.
The project itself is lighting up a 1/400 scale model of the Cunard Queen Mary 2.
I will be running this from a 3amp 12v power source using a range of mostly 3mm LEDs along with some 0402SMDs. They will mostly be in series chains of 2 or 3, with each chain having its own direct connection. I've grouped the LEDs into like for like, so no chain is made up using different colours or types/makes.
I've broken this all up into 5 layers, depending on where the lighting sits within the model vertically.
Below are 6 images. The first 5 are each layer individually, with the final one a combination of all 5. (Please Note: There may look like there are some broken or random wires, there isn't that is just me making crude use of the software to create an outline of the model)
(The software states I will require 1.89A but my calculations come closer to 2.5A)
Should I fit a fuse? If so, what value?
I'd appreciate any input, but please keep in mind my knowledge is absolute minimum, especially where terminology is concerned, thanks.
Edit: I've corrected the resistor value on the single red LED on layer 3, to 560ohm.
