It's important to remember that every LED needs a suitable resistor. Failure to do so will result in irreversible damage. Not sure which resistor to choose? Learn how to choose the right resistor for your LED !

5mm LED Diode Kit - justPi - 100 pcs.

The set contains 20 diodes in five colors.

How to properly install 5mm LEDs?

Installing 5mm LEDs is very simple, but requires maintaining correct polarity. The longer pin is the anode (positive) , and the shorter pin is the cathode (negative) . Always connect diodes with a current-limiting resistor to avoid damage—typical values range from 220Ω to 1kΩ , depending on the supply voltage . The diodes can be mounted directly on a breadboard or soldered to a PCB in final designs. Ensure the voltage and current match the diode's color specifications to ensure long life and stable operation in the circuit.
