There are many reasons to build your own Arduino circuit on a protoboard or a custom-designed printed circuit board. At the heart of the Arduino platform is an AVR microcontroller, in usual way you ...

By repeatedly taking the microcontroller through a couple of freeze-thaw cycles, [Edward] was able to calibrate this watchdog timer to a resolution of about 0.0025°C, which is more than enough ...

As every Hackaday reader knows, and tells us at every opportunity in the comments, adding an Arduino to your project instantly makes it twice as cool. But what if, in the course of adding an Arduin… ...

Any microcontroller or single board computer like the Raspberry Pi would do, but for simplicity and because of all the sensor modules available for it, the Arduino was the chosen one.

Arduino microcontrollers have added Python to the range of compatible programming languages. Others can be used, and not just Arduino's own IDE app.

In this article, we won't control anything with output pins. Instead, the Arduino will communicate sensor data to a Linux notebook, over the USB line. Modern microcontroller modules, like the Arduino, ...
