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 [citation:1][citation:5][citation:8].
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 [citation:1][citation:5]
Typical forward voltage range: 1.6V to 3.4V depending on color [citation:1][citation:3].
The long lead is the anode (positive) and the short lead is the cathode (negative) [citation:5].
Always use a current-limiting resistor (typically 220Ω) to prevent exceeding the max current of 20mA [citation:1][citation:5].

This assorted set is ideal for Arduino and other MCU projects where you need clear visual feedback [citation:2][citation:5]. The different voltage requirements for each color ensure compatibility with a wide range of electronics [citation:3][citation:15].
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 [citation:5].
Inconsistent brightness:
- Adjust resistors per color as brightness can vary.
- Keep all LEDs within their max current rating [citation:1][citation:5].
