100 RGB LEDs = 300 control pins = 38 * 74HC595 chips (plus the needed buffers).That could look like a big mess.Addressable RGB LEDS is an easy/clean solution, and maybe cheaper in the end.No other chips needed. Just one resistor and one cap.Leo..
The han Ron ht1632c chips did an adequate job of handling the 384 lights, arduino folk ran with them all soerts of displays.
Addressable Rgb leds wow!that looks cool!Never heard of that
32 x 16 but we live in a 10-digit world...... 10 x 10I think the same folks who did this also makes hot dogs in 10 packs and rolls in 8 packs.
how many pins does it need?
One.A Neopixel is simply Adafruit's trade name for a WS2812.They are addressed in software a bit like a shift register. You have an area of memory with each byte representing one colour component of one LED. When your code has set these bytes then the whole lot is sent over one wire for the LEDs to pick up.
does there exist any Addressable Rgb leds cheaper than WS2812?
