The goal is to be able to fade up and down a v light.
MOC Technical Data
As you rise the voltage from Email Required, but never shown. Below is my circuit Vcc is 5v arduino pin: My circuit diagram is from the chip MOC figure 9 – pdf. Rvy Pandey 1 2.
I hope you got the point that you cannot dim using this circuit.

Post as a guest Name. Connect a ohm resistor as shown, and the problem of flickering when pin 4 is touched will be solved: Ravi Shanker 11 1.
Specifically which opto are you using? I’ve changed the formatting a little, but you could improve the answer if you explain how it solves it.
I suggest looking out ‘more’ on the internet might help you. As the voltage crosses 2. Connect a ohm resistor as shown, and the problem of flickering when pin 4 is touched will be solved:.

This simple circuit has now become the hardest circuit I’ve ever worked on Sign up using Facebook. I’ve spend days debugging this circuit and have exhausted all possible solutions.
I know it’s more stable to have one, but from my understanding the circuit should still work without one. The led will trigger the Triac driver inside, at whatever threshold it is supposed to trigger.
Sign up using Email and Password. See here The led will trigger the Triac driver inside, at whatever threshold it is supposed to trigger. Let’s say supplying 2.
The fade that you’re trying to achieve is not possible with this circuit or with whatever approach you are trying to follow here. I’m certain the components are working tested with multimeter.
I’m certain I soldered everything correctly.

MOC30XX is an opto-isolator. Has anyone been able to make this circuit work before? You can’t fade up and down the light without a zero cross reference. One weird thing is that when I touch the line between pin 4 and the gate with a multimeter- sometimes the light flickers.
I’m writing this down here because I was unable to comment on the question directly due to reputation. What is the source of your circuit diagram?
The issue is getting the photocell within the opto-isolator to trigger the gate of the Triac.
