We now know that a “ triac” is a 4- layer, PNPN in the positive direction and a NPNP in the negative direction, three- terminal bidirectional device that blocks current in its “ OFF” state acting like an open- circuit switch, but unlike a conventional thyristor, the triac can conduct current in either direction when triggered by a single gate pulse. EDIT: Several suggestions have been given in the answers. A 7805 voltage regulator is also used to supply regulated 5v to the circuit. To switch the AC current to the lamp, we have to use an opto- coupled triac, lamp and a diac is shown in circuit below. In this project, we will show how to connect an optocoupler chip to a circuit. Test voltage must be applied within dv/ dt rating.

That makes sense. Pricing and Availability on millions of electronic components from Digi- Key Electronics. Since the output is driven by a TRIAC we can drive loads upto 400V and the triac can conduct in both directions hence controlling AC loads will not be a problem.
