Re: Intelligent Pixel strips and power injection question
See without the +v at the other end, the electrons were getting too tired by the time they got all the way to the end of the string to be able to push through the LED. Injecting +V at the other end let FRESH electrons in and then slide home on the -V rail on a free ride.
Ok, I KNOW it is actually electrons being sourced from the -V rail because electrons are negative, but common current convention says the current flows from the positve to the negative so do not nit pick my little story..
