I have read Wendy's blog entry regarding the use of the 555 for PWM. Have also read the following topic regarding handling larger loads:

In my case, the load will be the following (5 meter, 300 LED led strip working at 12v, max 2A):

1) I would like to ask if the following Mosfet can be used instead of the IRF510, as it's what I have here:

2) I would also like to add a motion detector module, the HC-SR501:

I am not sure how to use it to trigger the 555 in PWM configuration ON when the sensor detects motion.
In the end I would like to have a led strip that I could dim to my preference and that would turn ON when detecting motion at night. It would be particularly useful if I could have a switch to bypass the motion detector system, when I need the leds to stay ON all the time.
