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.
Well I thought using the matrix algorithm you just need two shift registers.10*10=100
Addressable Rgb leds wow!that looks cool!Never heard of that but all I found all the Google was strip leds which I don't need it to be strip.So a link would be great Tnx.
ht1632c this looks to be a display driver I don't think so if display drivers can support pwm can they?I don't know how to work with them.i found a version
32x4 LCD driver
Costing 13 dollars I don't know for sure does it mean I can control 128 Rgb leds?13 dollars is fine for this I guess please explain more Tnx.
Thank you so much but the whole point of this question is to get Rgb leds work so dimming is definitely needed . Tnx for the edit yeah you're right I need to change the topic title and thing I'll do it Tnx.
