Some 230V questions - General Electronics - Arduino Forum

Hi all, I am building a running light that controls a bunch of 230V (LED) lights. I have tried it with relays, but they are too slow on the high speed settings. So now I'm switching to the MOC3021 optocoupler / BT136 triac combination. The main electrical difference is, that I now have to solder part of the 230V circuit. And that's what my questions are about.. Up until the MOC3021 it's all 5V. No problems there. But from the MOC3021 up until the actual light bulb, it's 230V. And in part of t
