the teensy will send a PWM to a voltage regulator,
which will then run these motors at different voltages to simulate the beat of the song to the motors
Your diodes are the wrong way round they will short out the supply as you have them.No that should not happen. Luckily your schematic shows no such thing.Not sure this will give you that result, my feeling is the motor's will just be a random mess.
How much current do these motors take? 2 motors per transistor seems risky. Also the 330 ohm base resistors are probably too large.
So what I'm getting from this is to flip the diodes.
The project has to work its for my final grade in my class.
I've been testing the mat
The motors take .3 amps each.
That is probably when running. You need to know the stall current. To find this, measure the resistance of the motor and use ohms law to work out the current for any voltage you apply.
To change the amount of amps the motors will get, this will be done within the code and through the use of the transistors in my circuit correct?
