LED Emergency Light Circuit
This is small project for making a LED Emergency Light Circuit. It help when power goes OFF which is very easy to build and does not cost much. We use these LED because it saves power and last for long time. Circuit Working: Parts List: Category Item Quantity Resistors 1k 1/4 W CFR 1 100Ω […]
Automatic Bedroom Lamp Timer Circuit
Automatic Bedroom Lamp Timer Circuit turns OFF by itself and this is a very cool idea. But first think about safety. Do not touch when it is plug in as It takes big power from wall. This circuit is not too hard. When we press button then many parts start working together. What is a […]
LED Chaser Circuit using IC 4017
This LED Chaser Circuit using IC 4017 project make LED lights turn ON one by one like chasing. It is fun way to learn electronics. One chip of IC 555 makes pulse again and again. That pulse connects to other chip IC 4017 and it turn ON and OFF each pin one by one. All […]
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. This circuit uses two BC547 transistor and they help red and green LED blink one by one. What is a Alternate […]
Simple Single Transistor LED Flasher Circuit
This Simple Single Transistor LED Flasher Circuit show smallest LED flasher circuit ever made. LED blink ON and OFF again and again by using only one transistor, one resistor and one capacitor. Just think of only one transistor and some easy parts and LED will start flashing, look nice! This is type of circuit one […]
