I have one Arduino and I need to be able to control five to seven 12V motors that each draw about 4 amps.
Would I be able to use four Sabertooth 2X5 Regenerative Motor Drivers for this? Each driver controls two motors and takes a 0-5V analog input. Would I be able to connect the input ground (for analog input) all to the same GND on the Arduino, and then individually connect each drivers' analog input to a PWM-capable Arduino output pin? Would that work? I'm a bit new to electronics, specifically linking multiple circuits like this.
Thanks for your help!
