LED Projects for Engineering Students

November 13, 2021 By WatElectronics

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...]

June 30, 2021 By WatElectronics

LED

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

January 11, 2021 By admin

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

July 4, 2020 By WatElectronics

RGB LED

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...]
