Connections
These panels are normally designed for chaining
(linking end-to-end into larger displays)…the output of one panel
connects to the input of the next, down the line.
The rear of the panel will have two connection points
On some panels, if you’re lucky, the sockets are labeled INPUT and OUTPUT (sometimes IN and OUT or similar),
so it’s obvious which is the input socket.
Mine has
Din (Data in)
+5V
GND
and
Dout
+5
GND
multiple panels can be connected either in Series or Parallel.
Links
Each LED in our WS2812 RGB LED Strips has a built-in micro-controller IC chip which allows you to daisy-chain the LEDs and control them individually - all from a single digital pin! The constant-current driver in each LED ensures that colour remains consistent, even if supply-voltage varies slightly from the optimal 5V.
we can control which LED should light & what colour it should be.
really cool.
