I have a Dotstar strip one it’s way to me, and I’m just trying to tie a circuit together so I can control it. The power regulator in the diagram is actually an Adafruit 5v 4a switching supply (also on it’s way!), and the RGB LED is the dotstar strip.
Also the switch at the top of the diagram (between +5 and the live rail) is actually a board jumper, so I can disconnect the controller from the positive rail to make sure I get no voltage leak into my computer while I am writing/testing.
Does the controller need a ceramic capacitor between +5 and G? If so, which side of the jumper should it go? Any other suggestions or advice? I’m trying to get it all ready in my head for when the strip arrives!
Many thanks in advance!
