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 ...

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 ...

Using the analog converter input function of a compact microcontroller’s input pins to read ternary logic encoding allows two pins to sense as many as nine configuration states. When designing with ...

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 ...

In the last installment of The GeekDad Arduino Guide, I introduced you to the Arduino hardware and why it is so cool. Now, let’s start actually using an Arduino. How do you get started? Well, first ...
