hi i am using a 12v power supply with my ez-b i started to get i little hot so i bought a 5v cooling fan for ez-b but my fan has 3 pin instead of 2 it has an extra signal wire does this make any diffrence i am thinking of connect fan to lets say d1 if i write set(d1,on) it should turn the fan on right?
Further information is here
why what happens if i connect it thanks for the response
Any way to read that pulse and use it with EZ-B? Output a tach reading?
It also makes me wonder why anyone would want this information.
FYI 4 pin fans have PWM control on the fourth wire if you wanted control over the speed.
