3 to 5 LED chaser circuits using Arduino, with control potentiometer

Have you ever built a LED running light circuit? Many people like these circuits, me too. I am going to show you how to use the LED chaser circuit using Arduino. We can easily apply or change coding. And once you know the working principle. Creating a 12 LED chaser circuit is also not difficult. … Read more

How to make fast blinking lights for bike


This is a fast blinking LED bike light circuit For safety when the bike at night. We use two-NPN-PNP transistor oscillator circuit and RC circuit only show on 4 LEDs use low current. We take the four LEDs to parallel. Because of each LED use voltage about 3 – 4.5VWe want this circuit for a … Read more
