Hello,

I would like to create a wind simulator using an Arduino Uno and multiple pwm fans. The wiki says that SimHub can control up to 3 pwm fans, and I'm assuming that it's due to the number of available pins on the Arduino for PWM control. This leads me to believe that the Arduino Uno can only provide two different pwm outputs, or two fans.

Could I control 4 fans using an Arduino Uno, with 2 fans connected to pin 9 and the other 2 to pin 10? Am I really limited to one fan per pin, or can I add as many as I desire (assuming the power supply can handle it).

I apologize if this is a silly question, but I'd really like to bring this idea to fruition. I'm not sure if there is something in the Arduino or SimHub that limits me to just 3 fans, or if it's possible to "split" the pwm signal like multiple chassis fans in a PC case.

Thanks so much for your time.

 

P.S.: I freaking love SimHub and I think it is a uniquely incredible program. It has revolutionized simracing and you should be proud of your work. I'm extremely pleased with its functionality, as well as its ease of use. Thank you!
