    Use opto coupler with triac output, something like a TLP3042, " 0" crossing; PN A10035, Electronic Goldmine.

    Please give more detail. Many people might think micro = microcontroller, and your reference to a program supports this, but depending on your language background you might as easily be talking about a microphone.
