    Appears to be a 555 chip with built in programmable timer.

    I have never used this chip or the programming module for it so im looking for some information.

    I need it to activate a relay if a tilt switch triggers it. This relay needs to be active for anywhere from 60 to 120 seconds. Then check if the tilt switch is still closed. If closed rearm again for the same amount of time and repeat until the switch is open or the battery dies.

    help is appreciated :)
