So the lone LED in the middle, with two resistors, is going to be on all the time, as a night light to the night light.
If the rest of the LEDs are on a switch, will I have to run two completely separate wires for the single LED, isolating it on its own circuit?
I’m tentatively planning on doing that, using heat shrink or something like that to tidy up the wires, then use two DC barrel jacks to connect each set of wires to the board. Are there any potential problems with this plan?
Yep, the power source is a 7.5V wall wart
Awesome well what i would do is have the power supply inside the wall (behind the switch) on a plug base, powered 24/7. Id then run: 1 cable up to the light as your negative. 1 cable up to the light as your night light. 1 cable up to the light as your switched positive.
Bonus: If you want the night light to turn off when the main light is on, just run it off the normally closed terminal of the switch instead. Either way - just 3 wires from the bottom to the top, all 7.5vdc.
Any grade of cable is fine since its extra low voltage. Jusy make sure its like 1mm2 or greater so you dont suffer from voltage drop. If you just have one or two of these lights any switch should be fine with that load.
Is that what you were wanting to verify?
