Code can be used also with 220v dimmable lights ?

Thanks

This code works only for DC current because it uses PWM. For 220V AC you need different HW with zero detection and optocouplers. But SW is very similar. Just use variable newLevel in example (value betwen 0 and 100%) to set light level in combination with zero detection. Google and you will find many examples internet.

EDIT: Lstt posted HW for 220AC
