I’m certain the components are working tested with multimeter. Connect a ohm resistor as shown, and the problem of flickering when pin 4 is touched will be solved:.
Below is my circuit Vcc is 5v arduino pin: Currently when I plug this circuit in – the light doesn’t turn on. My circuit diagram is from the chip MOC figure 9 – pdf.
I’m thinking that the voltage difference isn’t correct and that my probe is inducing datasgeet difference that allows the gate to be triggered for a very very brief moment.

I know it’s more stable to have one, but from my understanding the circuit should still work without one. Has anyone been able to make this circuit work before? I’m certain I soldered everything correctly.
Ravi Shanker 11 1. Specifically which opto are you using?

What does your zero-crossing detector look like? Post as a guest Name. One weird thing is that when I touch the line between pin 4 and the gate with a multimeter- sometimes the light flickers. Connect a ohm resistor as shown, and the problem of flickering when pin 4 is touched will be solved: Sign up using Facebook.

I’ve changed the formatting a little, but you could improve the answer if you explain how it solves it.

As the voltage crosses 2. The goal is to be able to fade up and down a v light. The issue is getting the photocell within the opto-isolator to trigger the gate of the Triac.
Email Required, but never shown. The led will trigger the Triac driver inside, at whatever threshold it is supposed to trigger.
