I found this article here **broken link removed**
I have a meanwell ldd 700 ma dimmable driver , how can I interface this circuit with the dimmer ?
the dimmer inputs don't have any polarity .
Also since the Vin of my dimmer is between 2.5 ~ 6V do I have to use the FET shown in the circuit ?

thanks

Nevermind, I found your other thread.

You don't need the transistor or R2. You can connect pin 7 of the 555 directly to the controller.
