5mm LED Assortment + Resistors

This 5mm LED Assortment + Resistors kit is designed for anyone who needs reliable, easy-to-use indicator LEDs for prototyping and electronics projects. The pack contains assorted 5mm round through-hole LEDs in multiple colours, along with resistors used for current limiting. A 5mm LED is one of the most widely used electronic components: it converts electrical energy into visible light when forward biased, making it perfect for status indication, learning circuits, microcontroller outputs and simple visual displays. Each LED has two leads: the anode is normally the longer lead and the cathode is normally the shorter lead, often also marked by the flat side on the LED body. LEDs must be used with a suitable series resistor to limit current, especially when connecting to 5V Arduino, Raspberry Pi GPIO circuits, battery packs or bench power supplies. Typical 5mm indicator LEDs are designed for around 20mA forward current, with forward voltage depending on colour: red, yellow and green LEDs are usually lower voltage, while blue and white LEDs are typically around 3.0V to 3.6V. The included resistors make this kit convenient for beginners and fast prototyping. Use the LEDs on a breadboard, solder them onto perfboard or mount them in panels for low-voltage indication. They are suitable for Arduino LED blink experiments, traffic light models, school science projects, DIY electronics training, control panel indicators, robotics status signals and decorative mini lighting. The round 5mm package fits standard LED holders and panel holes used in many hobby enclosures. Package includes assorted 5mm through-hole LEDs and current-limiting resistors. Colour mix and resistor values may vary by batch; always verify resistor value by colour code or multimeter and select the correct value for your supply voltage and required LED current.
