Looking for a simple circuit to control the light intensity of Light Emitting Diodes (LEDs) or similar lighting sources? Here is an Arduino based circuit with three independent pulse width modulated ...

I have spent at least an hour almost every day since the 80’s advancing my knowledge in electronics. Recently I brushed up my knowledge on LED fading secrets and attained something pleasant. Now, I’d ...

long current_time = millis(); //millis() - Returns the number of milliseconds since the Arduino board began running the current program. bool btn = digitalRead(BTN ...

This project demonstrates how to control the brightness of an LED using Pulse Width Modulation (PWM) on an Arduino Uno. The LED smoothly fades in and out by changing the PWM duty cycle on digital pin ...

Building IoT projects with touchscreens used to be a headache, involving numerous components, messy wiring, and endless troubleshooting. But the ESP32-S3 Box-3 makes things way easier. It is an all-in ...

Electronics enthusiasts looking for a way to add a retro LED matrix to their project may be interested in a new piece of hardware which is now available from the Adafruit online store, in the form of ...
