With all this someone had to note the fact that seems only two wires coming out of the motor ?!? If so, should be quite straight forward !!
In any case the addition of PWM is unnecessary and complicates the project, no to mention adding audible vibration and possible picked up audio noise. Who said you need to slow down the slewing at all? In fact I think the MC33030 chips are either off, full forward or full reverse until the feedback slider voltage matches your control voltage.
For example, in a 10 seconds fade in. With PWM the servo travels from one point to the other in a constant movement. What happens if I use digital?
Wouldn't the fader positions be in a MIDI / automation track? You wouldn't be calculating long-term fades on the uC, that'll already be in the automation data. You just need to go to a given position.Well, almost no calculation.. The only interpolation is how long it should take to get there (slew rate) given large or small differences from the current position, and whether there should be any non-linear acceleration applied.
I just got a 3 milivolt difference between touched and untouched status of the TS (feeding sensor with 3.3v from Arduino. Is too small difference, dont you think? Maybe is enough to pick it up with AD7147 chips Techylah reccomended?
