Strange question maybe but..
i need to make a very simple code for a "walking light" on a ws2812b 5050 rgb ledstrip.
meaning that one light will go on and off again when the following led goes on (so just one at a time on) i want this, as i need to cut off each separate led from a 144 leds strip (so into 144 pcs) and solder them together again.
i would like to have a quick visual confirmation buy running this code, so i can verify that the soldering connections are good (specifically the data line) as the 5+ and grounds are ofcourse easy to check.
but for this to work as i need to understand the following.
what will happen if i program for #144 leds but connect (any) number LESS than that and still run the code. ???
hope someone can give a simple answer on this.
don't worry about the why i need to cut them separate, it's really not important to the question just on the why i want to know, no 'solution' needed there.
