I wanted to build a circuit where i would be able to control 90 LED's using one WS2811 and have a total of 60 WS2811.
In this circuit I hope to connect 30 LED's per channel, there is no need for me to control the individual LEDs thus there is no point in me going for the WS2812s which is commonly used.
I tried a few circuits that i saw online (sorry! dont have the links) and not of them worked, all i ended up was buring two of the IC's, and the circuit which did work I was unable to turn off the LED there was always a small amount of brightness.
Working voltage: 12V No. of LED's per channel: 30
This is how the LEDs are wired
I believe this is the circuit that i used
EDIT 1: I tried this circuit as well but the output is very low (brightness)
I modified the above circuit to 100ohm at R1 and 10k ohm at R2, the transistor T1 is BC547 and T2 is BC817. After modifying the resistors and transistors, I am able to get a much higher brightness however, if I am to connect the negative directly to ground the Strip (the one i am testing with) consumes 1A current but via this circuit it is consuming only 600mA. Do i need to change T1 for better results?
