The central element in this switching circuit is a triode alternating current switch or triac. Pin number 1 is the anode and pin number 2 is the cathode as per the datasheet a 330 resistor is connected in series with the anode of the ir led. This triac based 220v ac motor speed controller circuit is designed for controlling the speed of small household motors like drill machines.
The setting of p1 determines the phase of the trigger pulse that fires the triac.
