🧠 How I Learned I used a combination of ChatGPT, YouTube, and online tutorials to understand Arduino basics — especially how digital inputs work and the use of pull-down resistors. This project is ...

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 ...

The circuit is the same for both games. It uses four different colored LEDs that are associated with four buttons, and it has a separate fifth start button. All LEDs and buttons are in series with ...

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 ...

When you read “Arduino wristwatch”, you fall into the trap of envisioning an Arduino UNO clumsily strapped to someone’s wrist. [Marijo Blažević’s] creation is much more ...
