In StockAn RGB LED is a light-emitting diode that combines Red, Green, and Blue LEDs in a single package. By adjusting the brightness of each color, it can produce millions of colors, making it ideal for decorative lighting, displays, and indicators.
Description
An RGB LED is a versatile and popular lighting component used in electronics and design. It consists of three separate LEDs—Red, Green, and Blue—either in a common cathode or common anode configuration. These colors are the primary colors of light, and by mixing them in different intensities, you can generate any color in the visible spectrum.
RGB LEDs are used in everything from TVs, smart lighting, and wearable tech, to DIY Arduino projects. They allow for dynamic color control, animations, and mood lighting. RGB LEDs can be manually controlled with resistors and switches, or digitally controlled using microcontrollers (like Arduino or ESP32) with PWM (Pulse Width Modulation) to set brightness levels.
Applications:
1.Smart Lighting
1.Mood lights, color-changing bulbs, ambient light systems.
2.Displays and Signage
1.Used in LED matrix displays and billboards.
3.Status Indicators
1.Show device state (e.g., red = error, green = OK, blue = standby).
4.Wearables and Fashion
1.Used in glowing accessories and reactive clothing.
5.Home Automation
1.RGB lights controlled via phone apps or voice assistants (e.g., Alexa, Google Home).
6.Gaming and PC Builds
1.RGB fans, strips, and keyboards for visual effects.

A Light Activated Motor Controller using IC 555 is a simple electronic circuit that turns a motor ON or OFF based on the presence or absence of light. It uses a LDR (Light Dependent Resistor) as a light sensor and the 555 timer IC in a comparator mode, along with an LED to indicate the motor’s status.

An Electronic Coin Toss circuit is an electronic version of the classic coin flip — often used to make quick decisions, settle disputes, or play games. It mimics the randomness of a real coin toss using digital logic or a microcontroller to generate a pseudo-random result and display it using LEDs or a text display (e.g., “Heads” or “Tails”).

A traffic light control circuit using IC CD4017 is a simple digital electronics project that mimics the working of a real traffic light system. It uses the CD4017 decade counter IC along with a timer (usually 555 IC) to sequentially switch Red, Yellow, and Green LEDs, simulating the flow of traffic signals.

A Battery High-Low Monitor is an electronic circuit or device that detects and indicates the voltage level of a battery — whether it’s too high (overcharged), normal, or too low (discharged). It helps protect batteries from overcharging or deep discharge, which can damage the battery or reduce its lifespan.
These monitors often use comparators, voltage dividers, LED indicators, or microcontrollers to track and display battery status in real time.

An XOR (Exclusive OR) gate is a digital logic gate that outputs true (1) only when the number of true inputs is odd. For two inputs, the output is high when the inputs are different. XOR gates can be constructed using basic logic gates or directly with transistors (BJT or MOSFET). Using transistors, we can design compact, efficient circuits for custom digital logic applications.
