Hey everyone, I am new to arduino and recently I have been messing with some dumb arduino non-addressable strips. I am currently doing a project with them where I am trying to control 14 individual strips using pwm signals. For expanding the pwm outputs in the arduino I have used 3 PCA9685 boards chained together giving me 45 pwm outputs and as the driver to the LEDs I have used a couple of uln2003a modules connected to the PCA9685 boards. But to get a wider range of colors for these LEDs I have to determine the time each channel in RGB stays on for in the final parameter(a) of PCA9685.setPWM(1, 0, a); but I have not been able to figure this out since I am only familiar with the normal RGB format in which to each channel the maximum value is 256, can someone please assist me. All response will be appreciated certainly. For example how can I get Orange using this system?
