An LED is a light-emitting diode. Lighting an LED is considered the "Hello world" of a circuit design, and it can be as simple as using a series resistor, or it can get more complicated, involving PWM and multiplexing.

Limiting op-amp-as-comparator output voltage (or, how to drive a LED without blowing it up)
I've got a 1 ohm sense resistor wired up between the indicators and ground, so what I'd like to do is turn on a LED whenever the sense voltage exceeds e.g. 40 mV*. … My current idea is using LM358AMX as a comparator (since I have those readily at hand), and then have a voltage regulator, current limiting resistor and the LED in series on the output. …

Small footprint constant current source / voltage regulator [closed]
I'm using 24 white LEDs, and since I don't want to work with huge voltages, my plan is to divide them into four 6-LED circuits, driven by a constant current source from 24 V, 20-30 mA, depending on how …
