My project is to have a 12V solar LED strip lighting system throughout my apartment. This has 6 individual lights, with 5 white and 1 RGB = 8 channels.
I've got the whole setup working on my breadboard. Now it's time to transfer it to a "live" setup. Since it's my first such project, I'm looking for any and all recommendations on cabling and connectors to deal with reliability, isolation, modularity, aesthetics and of course safety.
Schematically, it all looks something like this
solar panel------\ charge controller--5v regulator--arduino--mosfets x 8--\__lights 12v battery_fuse_/ \____________________________________/
So I have questions such as:-
- should I use a prototype shield, or a discrete pcb?
- do the MOSFETs (RFP30N06LE) need a heatsink, and any recommended unit?
- what connectors are recommended?
- any suggestions on box/packaging for the above?
- wire gauge? Maximum run is 4m to the furthest light.
And any other hints, tips and suggestions greatly appreciated. Bonus appreciation for amazon links to the parts :-)
update The breadboard is simply the mosfets, each with a current limiting resistor on the gate. The lights range from 8W to 40W. I will generally have them dimmed using PWM.
