Hi~ Thank u for any assistance...
I'm wanting to build a circuit to power (1) 3.8 volt, 20ma, l.e.d. & I've never built a circuit designed to provide a steady, adjustable power supply. I have immediate access to any specific component needed to build this circuit but I do not know exactly what I need to utilize or in what order the correct components must be organized. I want this circuit to originate from a standard 110volt a/c plug & I don't want the l.e.d. to fluctuate in brightness.
Can someone inform me which components I need & in what order I need to layout this circuit, please?
