Hello, I want to create a motion using electricity, using the cheapest means possible (DIY). Basically I'm trying to rotate an object 90degrees when the current is on, and back to its original position when the current is off. The questions are: 1) Is this possible? 2) Can this be done using 5V? 3) What is the easiest way to achieve this, through magnets? through a bimetallic strip? (i'm more interested perhaps in the magnet option, maybe looping a wire around a metal small bar and connecting a current through it that can be controlled by an on/off switch, and in this way enlarge the magnetic effect, but i'm not sure exactly if this works and how strong it is). Thanks!
