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’ ...

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.

Most projects are built on abstractions. After all, few of us can create our own wire, our own transistors, or our own integrated circuits. A few months ago, [Julian Ilett] found a problem using th… ...

An Arduino is a much better choice than a Raspberry Pi for tasks that require real-time input and responses. While a Pi can ...

What was your first Arduino program? Probably an LED blinker — that seems to be the “hello world” of microcontrolllers. You probably moved on to things a little more complicated p… ...

This module is modeled after an Etch A Sketch and combines Arduino and Processing sketches. With the help of Processing, you can trace a line using two controllers (potentiometers). One of the knobs ...

Whether it's your first time practicing coding, or you're a seasoned tinkerer, Arduino is an excellent platform to get your hands dirty with coding and tech.

Arduino simplifies things by only using just one coding language. Here's what you need to get started with developing software for the tiny device.

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 ...

An Arduino is a popular open-source single-board microcontroller. Learn how to program one and let the possibilities take shape.
