Code in the Arduino sketch is then used to compute the actual voltage ... So, in practice, it is better to label this voltmeter as “0-30V DVM” to add a safety margin!

There’s serial output under the source code, but it doesn’t scroll ... the comparator output and the connection to the Arduino’s analog converter (A0) are labeled nodes from the “Output ...

Save for the ports, everything else is labeled ... where the Arduino Integrated Development Environment (IDE) comes into the picture. It's an app primarily used for writing the code and ...

When you start on larger projects, say you upgrade to a Due or Teensy for more code or memory space, the Arduino IDE can hamper your productivity. Moving beyond these limitations requires a new ...

The on period, known as pulse width, is modulated (a.k.a. changed) via the code, allowing you to control the value sent to your components. PWM pins work the same way across all Arduino boards ...

We'll outline the basics of the Arduino itself, what the crazy jumble of wires means, and then step through how to use other people's code and schematics to build your first electronics project ...

The official Arduino IDE is a dour piece of software designed for uploading code to the ubiquitous and super-cool micro controller. It is a standalone, non-networked app that isn’t very pretty ...
