I am making an LED circuit for a Lobot (from star wars) costume headset that will not be on a PCB or stripboard. It will all be running inside the walls of the plastic shell I am making. Please see Gif of what I am hoping to do:
The LEDs will run through 4 different programs. Here is one program as an example:
-Far left and right led pairs will alternate on/off -Single LEDs will blink twice then off for a cycle -The (4) pairs on the left and right will rise and fall like a soundboard -The (3) pairs of white(blue in the demo) will chase bottom to top and back down again
I am new to electronics so I am a little nervous about running the ground wire for it. Here is my circuit:
The reds were switched to blue for the simulation but will actually be white. So they are 3v each but running in parallel will need 100ohm.
Now that we have that out of the way, is the ground wire run correctly?
The simulation runs perfectly, but I want to make sure that I am not overlooking something important before I try it on my arduino IRL. Is there a neater way to do this? Google searches availed me not. What is the accepted method for this type of circuit?
