Topic: Control 230V dimmable bulbs (Read 1 time) previous topic - next topic



To complete a lightning project I'll need to control 3 circuits each with with different kind of dimmable bulbs, I've no major issues on programming, but what for interfacing Arduino with 3 independent 230V controllers ?

Thanks a lot.


Do you have a specification on controllers or link to ?


Basically you need to send some PWM signals out to the controllers. However, depending on what the controller needs you might have to put the PWM signal trough a transistor.


3 off SSRs rated for logic level input.  Then drive them using PWM


I have the same problem with my project. I think you should use a high-voltage transistor, but i don't know which one. There are lots of different types of transistors, and i only know about low-voltage ones.

If somebody knows something about what type of transistor could we use... :~
