One of the earliest circuits in home electronics is the venerable incandescent AC lamp dimmer. It is also one of the most challenging circuits to get right. In this tech-nical brief we will examine how using a microcontroller can both simplify the circuit and make it efficient. THEORY Early dimmers were very simple circuits, not much 3 channels This circuit can also be used for an RGB mixer, albeit you need two additional TRIAC circuits. You could use this circuit+PCB in duplo for that, but make sure you use a random cycle opto-coupler suah as the MOC3021. Do not use a zerocrossing Opto-coupler such as the MOC3041.
