AC LED driver circuits are overly popular due to the advancement of High current white LEDs. We already made a Transformerless LED driver circuit previously, but in that circuit, we used a dedicated ...

Before explaining the PWM generation on ESP32, let’s discuss some terms associated with PWM. TON (On Time): The duration of time when the signal is high. TOFF (Off Time): The duration of time when the ...

In this tutorial I am going to create a Police Light themed LED Flashing circuit using the 555 timer IC. My 5-year old son asked me to create a Police Car like flashing light that he can put on top of ...

This article introduces an emergency LED light circuit, based on the SOT23-6 MP3202 chip, than can be powered through USB Type-C interface. Nowadays, LED technology is vastly emerged and LED-based ...

Since the earliest versions of indoor LED light bulbs were developed, their designers have faced a variety of technical challenges. These include AC-to-DC power conversion, thermal design/heat-sinking ...

In this simple but effective project, you will learn how to make a simple circuit using a 9-volt battery, LED, and pencil drawing. This project is a fun way to explore and learn about the science of ...
