No, we do not have simulation for our DIY project. Only real hardware and example code 8-)

Most likely you will need, because direct IO can only source or sink ~20mA if I am not mistaken. Most fan will require more than that :mrgreen:

Yup, you will need a driver or mosfet or transistor to drive the fan, due to the voltage and current requirement from the fan.
