3 colour portable LED Light Box wiring - Please Help Newbie Answered
I am building a portable LED Lightbox with a few rows of LEDs amounting to about 400 different coloured LEDs (red, green, white). Each row will be connected parallel as I want to use normal batteries to power it and not have too many wires. Ideally it should use AAA batteries and 1 switch to switch it on.
Each row will consist of 15 - 30 lights each. Each row will be the same colour (eg. 1 row red, 1 row green, 1 row white).
My question is:1
(1) Should I connect all the lights together and hook it up to the same battery pack? OR
(2) I should connect just the lights on each row together and wire all the positive of each row to the battery pack. Will it cause a short circuit since there will be many wires to just 1 battery pack.
(3) I have tried and each LED can be powered by a 3V battery, but is 3V enough to power 400 LEDs in parallel?
(4) If it is not enough, I could power a few rows together meaning I will have a few battery holders, but can all the battery holders be joined to just 1 switch or I need many switches as well?
