TinyDuino Processors & TinyShields / TinyDuino + Motor TinyShield

« on: May 23, 2014, 02:25:20 PM »

From my other post you may have seen that I'm trying to figure out how to create a "custom servo" using a motorized fader.

I'm now considering the possibility of doing this with the existing tinyduino units. If I connect a Tiny Motor Shield (4x) to a TinyDuino, I would theoretically be able to control 4 virtual servos.

There are then 3 questions:

1. With a motor shield attached, are there any remaining analog input pins that I can use for monitoring the slide pot?
2. Is there any way to network multiple TinyDuinos together?
3. Would the "lilly" version of TinyDuino / Tiny Motor be a better fit for this approach?

New Product Ideas / Custom Servo Controller

« on: May 22, 2014, 02:30:41 PM »

I'm trying to control a massive array of motorized faders (like these: http://www.alps.com/WebObjects/catalog.woa/E/HTML/Potentiometer/SlidePotentiometers/RSN1M/RSN1M_list.html ).

I'm able to control them manually by reading the analog in from the slide pot and controlling the attached DC motor with a PWM motor controller. This works fine for a few, but when you get up to 100's it starts to get really inefficient.

I'm wondering if a custom servo type IC would be the solution. Something kind of like your motor controller, but with an analog input (for the slide pot) and enough on-board smarts to use a PWM position signal to drive the motor to a specific position - basically turning the whole assembly into a standalone Servo.

Is this something that's possible? If so, our company would use about 500 of them (!)
