A few months ago, [Julian Ilett] found a problem using the Arduino library for PWM. Recently, he revisited the issue and used his own PWM code to fix the problem. You can watch the video below.

In this tutorial, T.K. Hareendran shows us how to set up an interleaved PWM output on an Arduino Uno. He then uses different techniques to validate that the desired result is achieve.

The PWM sketch works to vary the output linearly, however, the light outputted by the LED does not change in a linear manner. When applying the scientific metric of ‘perceived brightness versus time’ ...

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… ...

Arduino Gemma from Adafruit is also based on the ATtiny85, and PB0 and PB1 appear to be accessible. This board has a USB connector for programming and a voltage regulator. This board, which I am ...

Arduino offers a simple framework to programme some AVRs in something like C but, without extra work, only allows PWMs to work at under 1kHz. The AVR used in the Arduino Leonardo and Micro is the ...

A new fully featured Arduino development board has been created called the Prestissimo Uno+ which is now available to back via Kickstarter with earlybird ...

Arduino enthusiasts or those looking to build a binary clock may be interested in a new shield created by developer Marcin Saj. The binary clock shield ...
