hey everyone… wondering if anyone can offer me some advice on a component…
I want to basically dim a single colour led using a digital pin out and then pass that data onto the next LED. Currently my circuit for one LED draws 6.4mA on a single pin. If I want to keep daisy chaining, this will limit me to 5 LEDs. Does anyone have any advice or point me in the direction of a circuit that will replicate/boost the PWM single to pass through.
I had considered a single WS2811 IC, and only using a single channel of it… maybe someone knows of a similar component that is single channel?
Thank you in advance…
Don’t power the led from the arduino pins. Only connect the data and gnd to arduino.
Thank you for the reply… Sorry not clear, the data pin is driving a transistor(s). That is where the 6mA reading comes from. The led is powered from a separate 5v supply.
In that case use a shift register and a Darlington IC.
On the other hand the WS2811 may be the easiest to use.
cool, I’ll check out the darlington, otherwise ws2811 it is.
