One of the first projects that most people do on an Arduino is to light up or flash an LED. It seems ultra-simple because it ...

In this experiment we are going to use a element called photoresistor. This sensor allows us to interact with the external environment, through intensity of light. The photoresistor is based on light ...

This is a simple 0 to 9 counter circuit constructed using Arduino! Here, a common cathode 7-segment LED display is connected to Arduino for displaying the digits. The code (Arduino sketch) allows push ...

Maybe it’s just us, but isn’t it kind of amazing that in a world of pretty darn realistic games, PONG is still thrilling to play? This 1D implementation by [newsonator] is about as exciting as it gets ...

[Credit: Djandco on Instructables] The Look of Disapproval (made using the unicode character for the letter “tha” in the Indian language of Kannada and an underscore) is possibly my favorite ...

Learn how to control and blink multiple LEDs using the MAX7219 driver with Arduino. A simple guide for beginners in electronics and coding. #Arduino #MAX7219 #LEDProjects #ElectronicsTutorial ...

It is a pretty common first project to use an Arduino (or similar) to blink an LED. Which, of course, brings taunts of: you could have used a 555! You can, of course, also use any sort of oscillator, ...

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 ...

In what follows, we will refer to these collections as “Breadboards,” “Tools,” and “Components” for short. For example, when working with semiconductors such as transistors, diodes (including ...
