This project is a great way to combine electronics with visual effects. It uses 12 individual LEDs that light up progressively based on the sound intensity captured by a microphone module.

This project describes the implementation of an Arduino-based reflex game designed to measure a user's reaction time to a visual signal displayed on an LCD. The system uses an Arduino Uno, a 16x2 LCD with I2C interface, and a push button for user interaction.

Do you remember the dinosaur game? And all the nostalgia it brings? Well, today I'm going to build one using an Arduino. We'll use the Wire and LiquidCrystal_I2C libraries. To adjust the contrast so you can see the image, there's a potentiometer on the back. Turn it gently with a screwdriver until the image becomes visible:

Photoresistors are simple but extremely effective components, capable of converting light variations into electrical signals, making them ideal for security projects such as a laser alarm. This project is very easy to build and low-cost.

Discover how to control a mini LED bar graph display using Arduino. This step-by-step tutorial shows how to light up each segment, making it an ideal project for beginners and electronics enthusiasts. This project is very simple to build, and you can also use 10 individual LEDs instead of a bar graph display.

DC motors (direct current motors) are some of the most commonly used components in electronics and Arduino projects, making them ideal for driving robots, toy cars, and other simple mechanisms. In this article, I will show you how to control a DC motor using the L293D motor driver.

In this article, I will explain how a breadboard works. People who are new to the world of electronics have probably never heard of it. That's not a problem—you'll understand what it is and how it works right now.

Did you know that you can turn sound into digital signals? Well, now you do. In this article, you will learn how to control an LED just by clapping your hands.

I've already told you how many interesting things you can do with an ESP32—and this is just the beginning. Using this project idea, you can control various devices, relays, and more with a simple ESP board. Here, everything is kept simple: it's just an LED controlled from your phone… but it's still pretty cool.

This article is for those who are new to this world. I believe it is important to also create tutorials like this for people who need them. Don't worry, it is very easy to use.

This is a very cool and easy project to build. On top of that, it's also fun. You can find the video on Instagram: here.

Did you know that you can turn an ESP32 into a mini web server? It's perfect, for example, for testing websites, or it can simply be used as a fun project.

RGB LEDs are electronic components that can display multiple colors by combining three internal LEDs: red, green, and blue. By controlling the intensity of each color, many shades can be created, including white.

This is a practical project that you can use as an alarm system. In the images above, the circuit is not clearly visible, but it is the same as in the schematics. The only difference is that I used an Arduino Nano.

This project is simple and easy to build, even for beginners. I used a ready-made traffic light module, but you can also use three separate LEDs. My traffic light already had the resistors built in, but if you use three LEDs, I recommend adding three 220Ω resistors.

This is a simple project to build, perfect for beginners as well as for those with more experience. And the best part is that it's very accurate. It showed 22.2°C and 57%, just like a thermostat.
