For my wedding I'm making some letters which I would like to provide with some LEDs. To have the full "I made this myself" experience, I gave myself a course on electrical engineering (google ftw), and started designing a circuit that could work with the materials I had lying around.
I've designed the circuit with some parallel LED "strings" connected in series (each RGBW series represents a letter,) but have too little experience with electrical engineering to be 100% sure it works. I'm sorry for the very amateuristic design, I hope the essence is still made clear.
If you guys could comment on whether I wired everything correctly, and used the appropriate resistors, that would be great!
Some more specs that came with the LED:
I based it all on theory, but am too hesitant to bring it into practice.
The 3 main points I am concerned about are:
- Is each color LED (which I combine before the MOSFET) still parallel, or do I effectively make them all in series by combining them before the MOSFET?
- Should I put the R1,2,3,4 resistors before the MOSFET, and maybe even after each "parallel string"(not sure about the technical term) before they are combined?
- Are the ohm values of R1,2,3,4 correct as designed at the moment, or are those values only valid when I apply my second bullet?
I've decided to keep the LEDs for other projects (probably being: catching dust in the cabinet) and buy a couple of WS2812B LEDs, so I can make a MUCH easier circuit (probably more on my level anyway).
