Hey all, Im working on a project where i have a teensy controlling a usb fan based on a temperature sensor. I have the temp sensor working with my teensy++ 2.0 using I2C, however Im not entirely sure what the best way to turn the fan on and off would be. The fan is literally only using the 5V power and ground pins to run.

thanks
 
A teensy can not drive a fan directly, but it can drive a FET or transistor that can drive the fan.
