How to use led?

i don’t know how to use leds

Connecting an LED to a circuit is straightforward, yet it’s crucial to include a resistor to prevent the LED from burning out due to excessive current. In this design, attach one end of the resistor to the electronic circuit. Then, connect the other end to the LED’s wire. The resistor effectively limits the current, protecting the LED. We’re using the DCACLab breadboard for simplicity, allowing easy component arrangement without soldering.

An illustration of this circuit with the LED and the essential resistor is provided below.
