I am looking to develop a program which utilises Ableton's (a digital audio workstation) Arduino connection kit (which needs Standard Firmata uploaded to the arduino) to control the speed of a stepper motor in real time.
The aim is to control the speed of the stepper motor with the amplitude of an audio file playing in real time.
Before I embark on this is anyone able to advise on the feasability of this project? I feel like it could be done with two arduinos - one to read from Ableton, then sending the PWM signal from a Digital PWM PIN to another Arduino with the Stepper attached.
Look forward to hearing any advice you may have!
