8×8 LED Matrix modules are now widely available, and fortunately they are easy to use with our favorite Arduino microcontroller. 8×8 LED Matrix module have many applications in real life, such as ...

Regular candles can be awfully boring at times. They can only produce one color and the flicker is so… predictable. They can’t even be controlled by an infrared remote control, not to mention the ...

Looking for a simple circuit to control the light intensity of Light Emitting Diodes (LEDs) or similar lighting sources? Here is an Arduino based circuit with three independent pulse width modulated ...

Sure, the physical build itself looks great, but it’s what [Michael] did with the firmware that impresses us the most. He’s using an Arduino Mega to drive the 7x7x7 cube and manages to squeeze out ...

This project demonstrates how to connect and control an external LED using an Arduino Uno. It’s a simple and fundamental project that introduces the basics of digital output. In this project, an ...

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 order to recognize colors from a video input, this project employs a Python script using OpenCV. A byte of data is then sent through the serial connection between the Arduino board and the local ...

Discover how you can build a professional digital multimeter using Arduino that measures up to 24V DC voltage, checks resistance, conducts diode testing, and performs continuity tests. This ...

Whether you’re an embedded systems vet, high school scientist, or a curious person, you need to start your electronic explorations somewhere. If the manual isn’t enough, then check out this beginner’s ...
