#defines can get quite complex but can make your code shorter and more readable. The Arduino IDE uses #defines to define things like I/O pin numbers, modes, and other things. You can also create ...

(Hint: there’s no Arduino-provided code involved; hardware registers and the __asm keyword show up.) If you learned embedded programming in an earlier era, this will probably seem glaringly obvious.

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 ...

The code includes two Arduino libraries ... except perhaps to change the pin configuration of the motors if they happen to run opposite to your command. Smart devices are everywhere these days ...

There are easy ways of getting more I/O pins for any project ... You can pick up [Dustin]’s code over on GitHub.

Arduino Cloud has introduced a game-changing feature, Collaborative Coding, designed to bring students, engineers, and IoT enthusiasts together in real-time coding environments. Gone are the days ...

This is a simple 0 to 9 counter circuit constructed using Arduino! Here, a common cathode 7-segment LED display is connected to Arduino for displaying the digits. The code (Arduino sketch) allows push ...

Code in the Arduino sketch is then used to compute the actual voltage being measured. The analog sensor on the Arduino board senses the voltage on the analog pin and converts it into a digital format ...

Youth ages 9-13 are invited by the EDC to participate in Arduino Coding, an after-school introductory course designed to teach the basics of circuits, robotics, and programming with a simple ...
