While waiting for my SFX100 motors to come from China (Ordered on Feb 1st still in HK! two months later!) so while waiting I figured it'll be a good time to sim wind running. Well I'm not getting power to the fans, I'm using some Wathai fans with 12v power supply. Followed all the Arduino Uno/shield setup but when I go to test fans don't spin despite Simhub's recognition of the setup so far. The fans are using a 4 pin config so just hooked up black and red but still nothing. Any help would be appreciated.
