RSA0N11M9A0J_motorised_slider
This project drives a model RSA0N11M9A0J motorised slider using a common L9110 H-Bridge driver.
It also allows using the built in capacitive sensor to prevent the motor from fighting manual movement.
There has three sections, a kicad circuit diagram, an arduino sketch using the capacitive touch library and lastly a few photos of it in action.
The specifications for the slider are available at (http://www.alps.com/WebObjects/catalog.woa/E/HTML/Potentiometer/SlidePotentiometers/RSN1M/RSA0N11M9A0J.html). These sliders were salvaged from a Yamaha M7 Audio Mixer (http://www.yamahaproaudio.com/global/en/products/mixers/m7cl/index.jsp) while it was being refurbished.
There are two sketches in the arduino directory. One for the attiny controller, another one with a basic i2c master for controlling the slaves. Each sketch includes a list of required libraries.
Improvements and changes cheerfully accepted.
