My goal: to deflect each axis of a two degree-of-freedom pointer compliant mechanism device with left and right channel audio signals.
I’m guessing driving the axes rotationally is not going to happen so I anticipate modifying the design to take the input of a linear electromagnet.
I’m throwing myself in the deep end with this project so appreciate tips on the following questions:
- Is my above assumption correct? i.e. linear motion will work, rotational not.
- Is it possible to drive a linear electromagnet / solenoid with an audio signal? e.g. if I were to play a sine wave at 440 Hz, I would get 440 Hz motion. I do not want to use PWM, this needs to be able to work with an audio output.
- Can this even be achieved without an Arduino? i.e. could I plug the output of my phone audio directly to the electromagnets to get motion, or is amplification absolutely necessary?
- If this setup is possible, what components should I be trying out and what type of setup would I be looking at, keeping things as simple as possible?
Happy to provide further clarification on the goals and intended setup, ask away.
Your help is much appreciated!
