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 ...

You can fade out and fade in the light of an LED automatically by using Arduino and a simple code that is described below. Even though the Arduino board cannot output variable voltage on its digital ...

a "~" sign, like ~3, ~5, ~6, ~9, ~10 and ~11. This example code is in the public domain. int led_1 = 11; // the PWM pin the LED is attached to int brightness_1 = 0; // how bright the LED is int ...

Arduino is an open-source electronics platform that makes it easy to create interactive projects. In the Arduino IDE, you can control LEDs, motors, and sensors using C++, with just a few tiny ...
