Arduino Modules

Adjusting a fan's speed using an Arduino is a great way to learn about PWM (Pulse Width Modulation) and motor control. With just a potentiometer and some simple wiring, you can create a smooth, manual speed adjustment system. This setup is useful for cooling electronics, ventilation projects, or any application where adjustable airflow is needed.

Motion sensors are essential in modern automation projects, playing a key role in security systems, smart lighting, and interactive devices. These sensors detect movement and trigger specific actions, making them useful for various applications. When paired with an Arduino, a motion sensor can be programmed to respond intelligently, creating an efficient and responsive system. This guide explains how motion sensors work, how to connect them to an Arduino, and how to write the code needed to make them function properly.

Connectors play a fundamental role in electronic systems by linking components together to ensure smooth power flow and signal transmission. The right connector can have a significant impact on the performance and reliability of any system. In this article, we'll explore some of the most commonly used connectors, discuss their features, and help you choose the one that suits your specific requirements.
