LEDs (Light Emitting Diodes) are fundamental components in electronics. They are commonly used for applications including lighting, communication, and indication, to name just a few examples. However, LEDs cannot regulate current and without limited current flow, they will eventually fail. In most cases, this can be solved by adding an appropriate resistor in series with the LED.
