Hello,
For a digital art project I would like to control a 16*16 array of small servos with a raspberry pi. However I can't connect all 16 channel servo controllers directly to the pi, so my idea was to connect the pi to a main controller which controls the servo controllers, which finally control the single servos. Are there such a "main" controllers, that are suitable for my case and if so, which one should I choose. It should be able to work continuously for a couple of hours.
Thanks in advance
Chris
