Hi all
I’m setting up a wind simulator using pwm fans using the Arduino uno to send signal to the pwm section of the fan. Power to the fans is direct via dc transformer. The Arduino cuts in and out as the pwm section of the fans pulling in too much power. What can I do? Someone mentioned to use resistor in series to the fan 1k to 4.7k ohms, would this work or reduce full power of the fans, ie Pwm not reaching 100 percent???
