Hello,
I bought a PCA9685 Board it is like the Adafruit 16 Channel 12bit PWM Driver.
I set it up and all works fine. I wrote a sketch with the Library from Adafruit. I hooked up a RGB LED Strip. Later I reconnected the power supply. There was no problem. But later I reconnected it another time and now I cannot set it all channels low.
The minimum values are the values of the color I had set before. I don't know how to reset the chip. I read that there are hard- and software possibilities to reset it.
Thank you very much in advance for your answer.
