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 ...

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 ...

Controlling LEDs is really quite simple. As you know, they need to be current limited which is as easy as applying Ohm’s law to your given set of values. To make things even more even there’s a slew ...

In this step-by-step tutorial, we're diving into the world of electronics and microcontrollers to create a personalized 8 by 8 LED matrix that can be controlled using an Arduino board In this ...

This is a simple flashing led circuit with 2 leds and 2 NPN transistors. It illustrates the behavior of transistors and capacitors and if you use an oscilloscope it will be very easy to determine what ...

Discover the step-by-step process of creating a powerful music reactive LED strip circuit in this comprehensive tutorial.

An LED dimmer circuit adjusts the brightness of LED strips, serving both as an energy-saving tool and a method to create aesthetic lighting. Call bells, designed to draw attention, are commonly used ...

I was following the Blinking LED Circuit tutorial from the docs but I got stuck after going through all the steps.

Issue #6558 suggests that maybe Pi Pico W isn't fully supported yet (😿) but I wanted to add that even the most basic sample doesn't completely function: import board import digitalio import time led ...
