LED and Lamps

This circuit uses a special chip 555 IC, normally used for timing things, in a surprising way. Here, it acts like a conductor controlling the flow of electricity to your LEDs. The chip creates a special pulsing signal square wave that gets sent through a transistor which acts like a gatekeeper for the electricity. This […]

This automatic doorbell light circuit is like a helpful friend for your doorway. When someone rings the doorbell, it automatically turns on a light right next to it. This makes it super easy to find the button especially at night or in the dark. So you can greet your visitors quickly and safely. Circuit Working: […]

This LED driver circuit, using the LT1932 chip, is like a special power supply for your LEDs. LEDs are a bit fussy about how much electricity they get, and this circuit makes sure they get exactly the right amount to shine brightly and last a long time. The LT1932 chip acts like a traffic cop […]

This is a special circuit that makes LEDs blink in pretty patterns. It uses a tiny timer chip to control the blinking on and off. You can use these blinking LEDs for decorations, art or to get peoples attention. By changing how fast and in what order the LEDs blink you can create different designs […]
