In my project I need to control the volume level through a motorized potentiometer; I guess I can have a compact board like BB to allow users to control the volume of an amplifier/mixer by means of custom Android app, installed on their Android phone.; for now I am thinking to use motorized pots from P3America Inc - they have pots controlled by (if not wrong) 4-5 V DC, yet to see if they have logarithmic ones . . .
In a nutshell, the idea is to have the user to connect his Android phone/tablet by means WiFi or RJ45 (home intranet network) to BB which is located inside the amp/mixer box (the box), and be allowed to switch the box ON/OFF, to control the volume, and ... for now let's speak only about the functionality to control the volume pot. The Question is: have anyone worked on a project where they controlled a small (servo-) DC motor (3-6 V) via Beagle Board, or any similar board (on www.digi.com I've seen similar, more expensive boards ) ? Possibly, to allow ability the BB board to receive a feed back from the motor unit about the current position (like 45 % of the MAX ), so the custom app can display it. The plan is to control the pot's power supply - I don't expect the BB to be able to directly supply power to the driving motor. Yes, this is too primitive a functionality for a compact computer like BB, but I will need it, because later it will also allow streaming audio/video, USB and SD cards mp3/ogg files storage. Thanks in an advance. -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups "BeagleBoard" group.
