Simple Automatic Bedroom Lamp Timer Circuit
Building a bedroom lamp timer that turns off automatically sounds cool but be careful. It uses strong electricity from the wall outlet so do not touch it when it is plugged in. The circuit itself is pretty simple. Pushing a button starts a chain reaction created by different parts working together. What is a Automatic […]
Simple LED Chaser Circuit using IC 4017
This project makes a series of LEDs light up one by one like a chase. It is a fun way to learn about electronics. A special chip IC 555 creates a steady pulse. This pulse tells another chip IC 4017 to turn its outputs on and off in a specific order. Each output of the […]
Simple Alternate Red Green LED Flasher Circuit
This post shows you how to build a flashing LED light circuit with red and green LEDs. These are popular electronic projects because they are fun and easy to make. The circuit uses two special parts called transistors to make the LEDs blink on and off in an alternating red green pattern. What is a […]
Simple Single Transistor LED Flasher Circuit
This article unveils what might be the tiniest LED flasher ever built. It uses just one transistor, a resistor and a capacitor to make an LED blink on and off forever. Imagine creating a cool LED flasher with only a single transistor and a few other basic parts. That is exactly what we are building […]
Simple LED Flashlight Circuit (Torch Circuit)
Forget bulky flashlights. Modern white LEDs are incredibly bright and efficient. They can light up the night with just 3V and a tiny amount of current around 20 mA. The following diagram shows a basic LED flashlight circuit. What is a LED Flashlight Circuit (Torch Circuit): A LED flashlight circuit also known as a torch […]
