Hello, I have a doubt that i couldn't find an answer to anywere...
So, we can use relays to control high voltage devices with Arduino,
but with this method we can just turn them on or off.
I would like to know what can we use to make those devices work at, lets say, 30% od 70% of their intensity (instead of 0% or 100%).
As an example, I would like to change light bulbs (60W) intensity with an Arduino, controling it glow more or less, depending on some condition. I would like to know how this can be achieved.
Thank you in advance.
