An LED is a two-lead semiconductor light source, which emits lights when activated.

When an appropriate voltage is applied to the LED terminal, then the electrons are able to recombine with the electron holes within the device and release energy in the form of photons.

This effect is known as electroluminescence.

The color of the LED is determined by the energy band gap of the semiconductor.

These red LEDs will provide your projects will light, instantly! Whether you need to indicate activity in your circuit or simply want to visual effects to your project, LEDs are simple to use and cheap to purchase!

Remember to never plug any LED directly to the power supply or it will destroy it! Ensure that the current through the LED is never more than 20mA. The easiest way to do this is to simply add a resister in series with the LED to reduce the Current to below 20mA. For example, if you have a power supply of of 4.5V then you would need to add a resistor of at least 50 Ohm to ensure the LED has less than 20mA of Current going through it
