Hi, i am recently research on a dimming incandescent bulb using triac BT138. i refer to the circuit connection of microchip:

i follow their circuit fully except the triac i am using is different. As i read through their circuit connection, they say they input the gate with PWM and i not so sure it works o not. till now, i just using multisim to simulate and i are unable to get my result. i am doubt on its circuit design.
can anyone help me and explain in more detail hows the circuit work or did anyone have any recommended or suggestion on how to control a triac dimmer using bt138. This is my first time using triac, thanks in advance for the help.
