3mm Mixed LEDs (4 Colors: Red, Yellow, Green, Blue)
= Standard Through-Hole LED Assortment for Electronics Projects =
This kit contains 3mm round LEDs in four bright colors (Red, Yellow, Green, Blue). These through-hole components are perfect for Arduino projects, status indicators, and other DIY electronics .
Four Colors in One Kit - Red, Yellow, Green, and Blue LEDs for status indicators, sensor projects, and creative lighting displays
Standard 3mm T1 Package Ideal for breadboarding and prototyping, with standard 2.54mm pin spacing
Typical forward voltage range: 1.6V to 3.4V depending on color .
The long lead is the anode (positive) and the short lead is the cathode (negative) .
Always use a current-limiting resistor (typically 220Ω) to prevent exceeding the max current of 20mA .

This assorted set is ideal for Arduino and other MCU projects where you need clear visual feedback . The different voltage requirements for each color ensure compatibility with a wide range of electronics .
= Troubleshooting =
LED not lighting:
- Check the polarity (long lead = positive, short lead = negative).
- Verify the forward voltage matches your circuit.
- Ensure a current-limiting resistor is installed .
Inconsistent brightness:
- Adjust resistors per color as brightness can vary.
- Keep all LEDs within their max current rating .
