Hi guys, can u guys help me on this?? I want to design and construct an automatic light dimmer circuit that controls the energy delivered to a 12V or 24V DC light bulb corresponding to the ambient light intensity.
The control of energy will be established through switching action to improve efficiency and i will use SCR as means for switching.
I have no idea where should i start. any ideas guys? thank u very much and hope to hear from u guys soon =)
