While a Raspberry Pi is a full-fledged computer that can do more complex things than an Arduino microcontroller, it's not the best choice for every project.

Raspberry Pi and Arduino are amazing on their own, but intimidating to learn. These nine coding and robotics courses help you get the most from them for $59.97, $363 off the $423 MSRP, now through ...

Running out of GPIO pins? Learn how to connect multiple buttons to just one Arduino pin using clever wiring and resistor techniques. Perfect for compact projects, keyboards, or when using small ...

The Arduino microcontroller takes over from there and executes your code on the Arduino. During upload, if your Arduino has an RX (Receive) LED built-in, you should see it flash rapidly as it ...

Hi, I'm Bill. I'm a software developer with a passion for making and electronics. I do a lot of things and here is where I document my learning in order to be able to inspire other people to make ...

Official Arduino Example Tutorials: The Arduino computer software is loaded with tons of examples for you to use in your own code or to run through as a learning experience.

Morse code can be sent using low power, equipment built from simple materials or even using mirrors or flashlights. Finally, Morse code is a very simple way to do covert communications.

Arduino is a do-it-yourselfers dream that allows you to create a true smart home experience tailored to your needs. Check out how to use Arduino to build the smart home you want.

That provides a professional development environment, at least. The code base for the Arduino is another frustration. Bluntly, the use of setup() and loop() with main() being hidden really bugs me.

The code to do this project, Richardson says, was “really easy.” In fact, it was a mashup between two projects he found using Arduino code.
