can i use product/1429 instead of product/1411?
i guess, i can connect 8 strip leds to product/1429 ?

1429 is not the best choice for driving strips. It does not have enough current to drive a full strip by itself, and the open-drain outputs are not ideal for interfacing with MOSFETs.

Re: RGB LED Adafruit 16-channel PWM/Servo Shield
I'm building a project that uses about a dozen servos, and the 16 Channel PWM/Servo Shield is working great. In this project each servo only moves once each 12 hours or so, the rest of the time they just sit there in their current position. I'd love it if I didn't have to keep the servos energized for all that time that they're idle.
The standard Arduino Servo library has detach(), attach(), and attach() functions to disengage and re-engage individual servos at will.
Looking at the documentation for the Adafruit-PWM-Servo-Driver-Library library, and at the source code on Github, it doesn't look like that functionality is available. Any idea how I could accomplish this with the Adafruit-PWM-Servo-Driver-Library library? Thanks!

Just set the pulse width to zero:
Code: Select all
pwm.setPWM(n, 0, 0);
