In this post I will explain this 220V RGB slow fading LED bulb circuit step by step and we can start from the left side and slowly move toward the right side so that you can understand what each block is doing. We use many parts like 555, 4017, 33uF, D1 to D4, and others […]

Light Emitting Diodes (LED) Explained
The full form of LED is Light Emitting Diode. LEDs are special type of semiconductor diodes which emit light in response to a potential difference applied across their terminals, hence the name light emitting diode. Just like a normal diode LEDs also have two terminals with polarity, namely anode and cathode. To illuminate an LED […]
Fading an LED ON/OFF – Arduino Basics
In this post I have explained a basic Arduino function where I have explained the process of fading an LED ON/OFF through some basic code implementations. Creating a Fading Effect We see how to use an analogwrite() function in order to implement a fading ON/OFF of an LED. The function incorporates PWM pulses across a […]
Single Transistor LED Flasher Circuit
It is possibly the smallest LED flasher to date, which is able to flash an LED ON/OFF infinitely using a single transistor, a resistor, and a capacitor. Can you imagine making a great looking LED flasher or blinker with just a single transistor and a couple of other passive parts? That’s exactly what I have […]
Simple LED Tubelight Circuit
An LED tube-light is lighting device built using high efficiency LEDs for illuminating a premise where it is installed, through the available AC mains supply. In this post I have explained the complete construction details of a simple LED light tube light circuit using 20 mA, 5 mm high bright white LEDs. The circuit can […]
How to Connect Car LED Downlight: Circuit Diagram
A car LED downlight available in the market can be easily integrated to an existing car battery if its rating is identical to the battery’s voltage rating. I have explained more regarding one such request sent by Mr. Allwyn Siqueira. How to Connect Downlight to 12V Car Battery Hi Swagatam, I’ve just spent the last […]
