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 ...

Making a blinking LED is most basic Hello World code for electronics. You just download Arduino IDE, open the example, choose the correct board and port, press upload ...

Before I start talking about this really cool thing called Arduino (Italian for "good friend"), let me say a few things about the fascinating subject of physical computing. Physical computing has been ...

Many of us know the basic Blink Arduino sketch, or have coded similar routines on other microcontrollers. Flashing an LED on and off—it doesn’t get much simpler than that. But how big should a blink ...

Before opening the Arduino software, wire up the Arduino according to the circuits page using the 8MHz minimalist breadboard circuit but with a 10k pull-up resistor on the reset pin (physical pin 1).

In our first lesson, we directly hooked up an LED circuit to the Arduino's 5V and 3.3V pins. While this enabled us to learn about Arduino's supply voltage and GND pins and gave us practical experience ...
