#24 Controlling a Fan by Measuring its Speed and Supplying a PWM Signal
This video shows how to use Arduino interrupts to measure the speed of a strong 4 wire fan. It shows also the steering of the RPMs by using a PWM signal. And it measures the transfer function of the fan.
The fan is part of my Wind Tunnel Project.
In the next video I will close the loop with a PI controller programmed into the Arduino to stabilize automatically a choosen RPM.
