A potentiometer is a simple knob that provides a variable resistance, which we can read into the Arduino board as an analog value. They can be attuned from zero ohms to whatever maximum resistance that is specific to it. For example, a potentiometer of 10 kΩ can be adjusted from 0 Ω to its maximum of 10 kΩ.
Ever wondered how your phone manages to stay charged without blowing up or how your TV remote controls those watching marathons? It's all thanks to a tiny but mighty electronic component - the resistor. Resistors are one of the most valuable parts of the tech world. These little wizards quietly control the flow of electric current in ways that make our gadgets tick. In this article, we're taking a deep dive into the world of resistors, from the magic of Ohm's law to cracking the colorful code that reveals their hidden values.
Laser modules emit highly focused beams of light, making them ideal for a wide range of applications. One of the key aspects of a laser module is its power output, typically measured in milliwatts (mW). Arduino compatible laser modules typically have a power output within the lower range ensuring safety and compatibility with the microcontroller board. It's important to note that modules require safety precautions due to their increased risk of eye damage and potential fire hazards for higher-power lasers.
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.

Light Emitting Diodes (LEDs) are incredibly adaptable components often employed in electronics projects for various purposes, from indicating status to creating captivating lighting effects. When it comes to managing LEDs with an Arduino, you have the option of utilizing either digital pins or Pulse Width Modulation (PWM) pins. In this article, we'll explore the advantages of each method and provide you with a comprehensive guide on how to control LEDs using an Arduino.
Shift registers are integral components in digital electronics, enabling efficient data management and transfer. When working on Arduino projects, you may quickly run into the issue of not having enough output pins to control all your components. This is where SIPO (Serial-In, Parallel-Out) shift registers come into play. These devices allow you to manage multiple outputs with just a few pins on your Arduino, making them a powerful tool for more complex projects involving numerous LEDs, buttons or other peripherals. This article explores why shift registers are necessary, how they function, and their practical applications with Arduino.
Arduino microcontrollers are the heart of countless DIY projects, from robots to automated systems. To bring these projects to life, you often need to interface them with motors. In this guide, we'll walk you through the essential steps of connecting a motor to an Arduino using a separate power supply while ensuring control with precision using an NPN transistor. This approach allows you to harness the full potential of your motorized creations without overloading your Arduino.
