A color flash LED is a small light-emitting diode that produces various colors automatically in sequence. Compared to single-color LEDs, this type of color flash LED incorporates the required components to emit several colors at a set rate, such as green, blue, and red, along with their combinations. This design allows it to flash a variety of colors automatically whenever someone powers it. People frequently use these in decorative lighting systems wherever they need an attractive … [Read more...]

KY-011 LED Module : PinOut, Features, Specifications, Interfacing, Datasheet & Its Applications
Day by day LED technology is progressing by creating Bi-color LEDs. This concept emerged as a method to use various colors in a single module to design more complex visual displays. Engineers call these bi-color or dual-color LED modules because they include two different colored LEDs in a single package. Electronics projects commonly use these modules when they need visual indicators with various states and special color indicators for user interfaces and circuit boards. Thus, examples of … [Read more...]
LED Traffic Light Module : PinOut, Features, Specifications, Interfacing & Its Applications
The first traffic light (stoplights or traffic signals) was launched in December 1868 in London on Parliament Square to decrease the requirement of traffic police officers to control traffic. These systems use electricity & computerized control with superior traffic light technology and improved intersection capacity. This system can also be used for purposes like pedestrian movement control, railway level crossings, and variable lane control like smart motorways and tidal flow systems. … [Read more...]
KY-010 Module : PinOut, Features, Specifications, Interfacing, Working, Datasheet & Its Applications
The photo interrupter module history is strongly tied to the IR LED development with the key innovation of both an LED and a phototransistor in a single package. It allows for object interruption detection by blocking the light path among them. So this concept achieved major traction with the mass IR LED production in the late 1960s. This is a transmission-type photo sensor including light emitting & light receiving elements which are connected by facing each other within a single package. … [Read more...]
LED Projects for Engineering Students
In LED projects, the term LED stands for light-emitting diode, which is a semi-conducting luminous source that works on the principle of Electroluminescence. LED was invented by Nick Holonyak in the year 1962. This bulb is constructed with 2 terminals like anode (positive) and cathode (negative) where the LED glows by transmitting power from an external source. They are available in multicolor and can be controlled with a remote. LEDs provide benefits in terms of less power consumption, are … [Read more...]

At present, one of the latest inventions in diodes is an LED or light-emitting diode. These light bulbs are used almost everywhere from cell phones to large display boards. Day by day, its popularity & its usage is increasing rapidly because of some extraordinary properties. In particular, light-emitting diodes are extremely small in size & consume less power. Generally, light-emitting diodes are active semiconductor-type electronic components. As compared to a normal diode, an LED is … [Read more...]
Scrolling LED Display Project Working with Circuit Diagram
We normally use a simple static LED display screen to convey a message. Earlier, when we want to display large data, we used to change message for every few instances. Now scrolling displays are more preferred to static. By using a pre programmed controller, we can make LED display in scrolling way. We can also make LED to adoptable by using PC controller based system. Simple Outdoor LED Message Moving or Scrolling Sign Board, Electronic projects using LED Scroller Generator for outdoor digital … [Read more...]
What is RGB LED : Circuit & Its Working
The term LED stands for Light Emitting Diode. In electronic circuits, the LED is a type of PN-junction semiconductor diode, which can emit light when current flows through the circuit in the forward direction. This indicates whether the electronic device is working or not. LEDs are widely used in various applications such as in cars, bikes, home appliances, offices, lighting, mobiles, televisions, etc. Usage of Multi-colored LEDs in the device reduces, cost, power and emits more than one colored … [Read more...]
