You are so smrt. I mean smart.

I assumed a DC fan would run slower at half of rated voltage and slower still at quarter of rated voltage. When I tried your test on my test fan, sure enough it...

I didn't have a coil so I tried the cap across the motor and voila!

Thanks.

I still can't get the fan to do three speed steps it's either on or off. Any ideas?

Using Sayzer's code, attached, I've been able to control an LED as desired.

Coupling that to a larger current drawing device is a problem. Of the schematic page provided, the top drawing has...

Ok forget about the FET and talk to me about the PWM signal. Should it be 5V pulses or 2.2V pulses? If 5V, what do I need to set to make it be that level?

Got the program and got the circuit set up. It seems to work well with LEDs but feeding the output to a FET, at least the FET I'm using, won't trigger the FET.

I looked at it with a scope and...

I have a couple of questions I hope you'll answer so I can understand what's going on better.

Why is it important to put the fan on gpio.2? I realize it's the "on-board pwm module" but what does...

You are my hero. I've yet to try it but I really appreciate your help. Thanks

Since you were able to provide an answer for that, do you have any ideas how I can run two outputs simultaneously but each at different output levels?

What I want to do is have a switch turn on a...

Thanks Sayzer,
I've had some other issues to resolve before I finally got to try it today. It works fine and does exactly what I want to accomplish.

I do have a few questions about how the...

Ladies and Gents,
I'm trying to use a 12F683 to control a fan motor. I want to be able to push a button and have the fan cycle through speeds from off to high in 3 steps.

The problem is I can't...
