Candy Vending machine, how to limit the amount of servos needed?
I got all the plans laid out and i got most of it working already.
The problem is: I want to limit the number of servos this project is using. Servos are expensive and they take precious pins on the arduino i'm using for the project.
The question is: I have 9 spirals for candy and i would need 9 servos to turn them and release candy (nom nom).
Is there some ingenious way to limit the amount of servos and still be able to rotate all the spirals independently?
This is basically what i'm making, just smaller :)
I edited it to include a little flash file i made of a rail system using 2 servos and an aktuator.
