Details
This Assorted LED Pack Red Green Yellow RGB is a practical optoelectronic starter kit for anyone building electronic projects in India. The pack brings together the most widely used indicator LED colours—red, green, yellow and RGB—so you can quickly prototype status lights, warning indicators, model lighting, Arduino outputs, Raspberry Pi GPIO experiments and basic STEM learning circuits without buying each colour separately.
These are standard through-hole LEDs, typically used on breadboards, perfboards and PCBs. A light emitting diode turns on when it is forward biased and sufficient current flows through it. Because LEDs are current-driven devices, they must always be used with a series resistor or a constant-current driver. For general 5V microcontroller projects, values such as 220Ω to 1kΩ are commonly selected depending on desired brightness and LED colour. Red and yellow LEDs usually have a lower forward voltage than green and RGB blue/green channels, so resistor choice should be calculated for each circuit.
The red, green and yellow LEDs are excellent for power, signal, alarm and mode indication. The RGB LED allows multi-colour output by controlling separate red, green and blue channels from microcontroller PWM pins, enabling colour mixing effects, mood lights and visual feedback projects. The longer leg is generally the anode on two-pin LEDs, while the flat side or shorter leg usually indicates cathode; RGB LED pinout should be verified with a multimeter before final soldering because common-anode and common-cathode variants exist in the market.
Use this LED assortment for Arduino Uno projects, breadboard labs, mini traffic lights, battery level displays, science fair models, robotics dashboards, electronic toys and decorative prototypes. The box/pack contains assorted discrete LEDs in red, green, yellow and RGB colours; resistors, wires and controllers are not included unless specified separately by the seller.
