Is there anything against testing the arduino motor shield with CPU fans? Reversing the polarity on the direction pin would cause my fan to spin backwards, right? Could the reverse spinning hurt this type of motor? Would the breaking feature work on these motors?I have 2 computer CPU fans:1 DC fan 12V, 2.1 watt, 0.18amp with only 2 wires (red, black)1 DC Brushless 12V, 1.7watt, 0.14amp with 2 wires (red, black, yellow)What is the yellow wire for?I think it sends pulses out when the motor is turning so it can be used as a safety feedback signal, as in "I'm telling the motor to turn but I'm not receiving any pulses back from it" error detection method.Lefty Thanks.
Are they safe to use with the motor shield? Does the reverse direction hurt this type of motor. Or otherwise said, how can I tell if these motors are bi-directional? Can someone confirm the last statement about the yelllow wire? Does anyone use this in their projects?
Now that you mention it, what is the H-drive? What is a H - Bridge?
