Once I used a TRIAC-based voltage dimmer with Raspberry Pi/Arduino to adjust the brightness of a traditional 220V light bulb. That particular dimmer was designed and sold by a local electronics online shop. Here is something similar: https://www.amazon.com/Light-Dimmer-Module-Arduino-Raspberry/dp/B06Y1DT1WP

What kind of AC bulb? Incandescent, CFL or LED type?
What is the power rating of the bulb?
