Analog Fading LED Answered
Hello - I am brand new to electronics but am trying to learn about BEAM and other art + science circuits. I am looking to make a small analog circuit to fade in and out a LED. I have looked online but have found a bunch of ones using a 555 timer or a PWM and other chips. I saw a reference to doing this slow fade in and out technique using only capacitors and resistors but have been unable to find a diagram. Can someone help me out. FWIW - I am looking to charge this using solar and am only looking to drive one LED. Ideally a days charge would last a few hours of fade in and out cycling with the cycle time being slow - somewhat like the Mac "Sleeping" LED. Thank you in advance.
