LEDs have come to the forefront of the market in recent years; investing in LEDs not only saves you a lot of money, but dramatically reduces the hassle of relamping and replacing units. With fluorescents gradually being replaced by LEDs, you may have thought the days of flickering lights were completely over. Though T8 LEDs are usually free of issues and flickering happens less often than with fluorescents, sometimes LEDs can blink, flicker, or even fail to turn on altogether. Generally, finding a solution to these issues is a relatively simple process. Read on for a few simple steps you should carry out to establish the root of the problem.

The functionality of LED is as same as normal diode but it emits light when current passes through it. It is used in most of the electronic circuits as a sign or visual representation to the normal human to know that circuit is working properly. We have lot of applications using LEDs. They are used in advertisement hoarding, Electronic devices, displays, night lamps, etc. All these circuits have been tested theoretically and published along with Schematics, Circuit Diagrams, Applications, Advantages, Limitations and the detailed explanation about circuit for each of them.
What Makes LED Lights Flicker? How to Stop LED Bulb Flickering
Once you've blinked a few LED's on and off a few times, you might think, what next? In this tutorial we will look at using a few LED's to blink in a programmable sequence which can look quite dramatic. The ATmega's pins are able to source enough current to drive a single LED, but we still need to limit the current to the LED so as not to damage it. The different color LED's available all have different voltage requirements so a simple LED driver circuit will need to be used, which is simply a single resistor which we will calculate further down the article.
Flickering of LED lights could be very annoying. LED bulbs and headlights can flicker in many situations. Sometimes a dimmer switch is involved, other times the flickering happens due to other technical reasons. In this article you will learn the root causes of LED flickering and how you can fix this effect. The intensity of the flicker effect may vary depending on the situation.
