I was looking for a way to dim a regular light bulb in a circuit. With the help of this site, I learned that using (variable) resistors would dim the light, but eat up electricity in the form of heat.
What I needed was a triac dimmer. I have been looking for a triac dimmer component, but failed to find anything that would fit my needs. What I'm looking for is something that is small and where a knob can be attached, much like a potentiometer.
Does this kind of component exist and how is it called? Maybe this kind of component is too big, and does not exist as a "kind of potentiometer".
Beginner questions from an absolute beginner. All help is much appreciated!
- this question is about AC power
- I want to make a lamp on a small block of wood with a knob to dim the light
