You may had saw to a complicated AC light dimmer circuit ago. Now let’s look simple, but useful, fairly good. This circuit uses a capacitor in series with one lamp and accessories with a bit more. Is used to control the light dimmer, Easy and cheap. Power was reduced,without interference, the switch S2 is an [...]

Working dimmer light bulbs Mechanic will cause a deterioration easy.And when using open or close the switch will cause a spark. But this cycle can be opened, adjusted and closed with a single point of contact.The IC number PT2102 make this circuit work 4-step is close – less light – medium light – very bright. [...]

This the circuit AC dimmer low voltage For lamp 6V. While this friends may don’t see the advantage of this circuit. But I thinks first step advantage be something get learn the work of Triac. And have tall safety , because of use AC Low Voltage. Which the work is simple be The UJT Q1 [...]
