WebMay 2, 2024 · This relay coils also needs a flyback diode since your MCU pins (and the transistor you use to drive it) are particularly vulnerable. Far more so than the relay you were asking about. Simple transformers convert AC-AC, not DC-DC so you can't power your Arduino the way you have drawn.

A flyback diode is any diode connected across an inductor used to eliminate flyback, which is the sudden voltage spike seen across an inductive load when its supply current is suddenly reduced or interrupted. It is used in circuits in which inductive loads are controlled by switches, and in switching power supplies and inverters.
