Experimentation is the food of enlightenment. You'd need a fairly large capacitor to provide any visible fade out effect. On the order of 1000uF, possibly more. You'd have to deal with the capacitor charging as well, and doing so without inducing a fade on effect would require additional circuitry.
This concept is called Fading of LEDs. Here is a simple circuit where an LED slowly fades out when it is applied with some voltage. The circuit mainly consists of a transistor and a capacitor.
The Capacitor discharges to the LED, allowing the LED to fad. The LED lighting disappears as the capacitor discharges. Then PIN 3 again goes big and charges for the capacitor and LEDs. In shopping centers, this can be used to fade out lights in areas where no crowds remain. In protection applications, fading LEDs may be used to warn something.
Like use the limiting resistor to power up the capacitor and then as the power dies down in the capacitor, the LED will fade. BUT I am hoping there is a simpler way, a hardware way. The use of the word "hardware" suggests not using an Arduino to drive the capacitor/LED system All these hardware talks is burning my mind. Ok, analogWrite it shall be.
Another resistor of 39KΩ is connected before the transistor, through which the Capacitor discharges. A 100KΩ Resistor is connected in parallel to the capacitor so that majority of the charge is discharged through the 39KΩ Resistor. Transistor used here is a NPN transistor of series BC548.
The slow-fade led circuit is very basic, 555 timer IC is used in the astable mode, and a transistor amplifies the current. The PIN 3 means that the power output is HIGH and LOW regularly at Astable mode 555 IC oscillates at a certain frequency.
