    Given a triggering event (PIR sensor), I'd like to trigger the following sequence:

    • Move servo to one side
    • Pause for 1/4 second
    • Move servo to other side
    • Pause for 1/4 second
    • Repeat the above four steps
    • Ignore input for 3-4 seconds

    I know I can do this with something like an ATTiny, but was wondering if it could be done with a handful of 555s.

    What do you think?

    Sounds like a job for a cheap 8-pin microcontroller and a few lines of code. :)
