You have probably been to a party where there is a strobe and it delays everything. Today we are going to use this principle to "slow" stuff (fans) down. Maybe you have seen one using 555 timers, the Arduino and maybe even the Propeller chip. However, have you ever seen one with a PIC?
We are going to build this today. I am using the PIC12f675 from Microchip. THer is a video below to show the inner workings.
