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 ...

An LED and a Serial Monitor connected to the Arduino. The user will input an integer value to the Serial Monitor, and the LED should blink that number of times. For instance, if the user enters 5, the ...

[Alex] needed a project for his microcomputer circuits class. He wanted something that would challenge him on both the electronics side of things, as well as the programming side. He ended up ...

Here’s an Arduino library that will let you drive a very large number of LEDs. [Elco Jacobs], an electrical engineering student, is the author of the library. He has a work-study job that has him ...

This software will let you write programs on your computer (using Python) that interact with an Arduino Uno. For instance, you might press a button on the Arduino that opens a web browser, or hit a ...

A buck-boost controller IC with four external switching MOSFETs can operate from input voltages above, below, or equal to the output voltage, enabling them to regulate the light output for a string of ...

Arduino has announced a Linux-capable version of its Uno, called Uno Q and based on a pair of processors: the quad 2GHz Arm Cortex-A53 QRB2210 from Qualcomm for the operating system, and the 160MHz ...
