Among all the Arduino boards, the Uno is most folks' go-to choice, and for good reason. It's the perfect platform to get started with Arduino, it's capable enough to handle a wide range of tasks, and ...

There are easy ways of getting more I/O pins for any project; shift registers, I2C expanders, or ADCs will give you plenty of pins for whatever project you have in mind. All these require extra ...

Abstract: In modern embedded systems, the demand for increased digital input/output (I/O) capabilities often exceeds the native pin count of micro controllers. One of the common solutions is the usage ...

Pin debouncer library for the Arduino platform, to filter out noise on an input pin. This library implements a non-blocking function to detect and filter out random state changes on input pins. The ...

I had cause to have a closer look at some Arduino inputs – it is that fascinating weather station again. It transpires that some Arduino inputs are better at tolerating slowly-changing inputs than ...

It seems that the Arduino is receiving either a 1 or 0 properly to set the direction pin to HIGH or LOW for clockwise and counter clockwise directions. However, the stepper motor still only moves ...
