Here, is small project for making a LED Emergency Light Circuit which helps, when power goes OFF and is very easy to build and does not cost much. Also, we use these LED because it saves power and last for long time. Circuit Working: Parts List: Components Values Quantity Resistors 1k 1/4 W CFR 1 […]
LED and Lamps
Automatic Bedroom Lamp Timer Circuit
To begin with, this Automatic Bedroom Lamp Timer Circuit turns OFF by itself and this is a very cool idea, but first we need to think about safety. Firstly, do not touch when it is plug IN as it takes big power from wall and also this circuit is not too hard. Moreover, when we […]
LED Chaser Circuit using IC 4017
This LED Chaser Circuit using IC 4017 project make LED lights turn ON one by one like chasing, also it is fun way to learn electronics. In addition, one chip of IC 555 makes pulse again and again and that pulse connects to other chip IC 4017 and it turn ON and OFF each pin […]
Alternate Red Green LED Flasher Circuit
This post show how to make a Alternate Red Green LED Flasher Circuit using red and green LED, it is fun and easy circuit, that is a reason so many people like this project. Also, this circuit uses two BC547 transistor and they help red and green LED blink one by one. What is a […]
Simple Single Transistor LED Flasher Circuit
To begin with, this Simple Single Transistor LED Flasher Circuit show smallest LED flasher circuit ever made, here the LED blink ON and OFF again and again by using only one transistor, one resistor and one capacitor. Now, just think of only one transistor and some easy parts and LED will start flashing, look nice! […]
Simple LED Flashlight Circuit (Torch Circuit)
This Simple LED Flashlight Circuit (Torch Circuit) is an easy circuit for beginner, it uses white LED, small battery and one push button. Further, when we press the push button, the LED produces bright light. The circuit also, uses only 3 volt and small current of about 20 mA to give light at night, hence […]
