Potentiometers: An Introduction and How to Use Them
Potentiometers, also known as pots, are variable resistors that allow users to adjust the amount of resistance in a circuit. They are commonly used in electronic devices such as audio equipment, lighting systems, and motor controllers. In this article, we will introduce the basics of potentiometers and provide a step-by-step guide on how to use them in your circuits. What is a Potentiometer? A potentiometer is a three-terminal device that consists of a resistive element, a sliding contact (wiper), and two end terminals. The resistive element can be made of materials such as carbon, wire wound, or conductive plastic, and its resistance is proportional to its length. The sliding contact…

Pulse-Width Modulation: The Art of Tickling Your Electronics
Have you ever wondered how your electric toothbrush or the motor in your drone works? Chances are, they use a technique called Pulse Width Modulation (PWM). PWM is a clever way of controlling the amount of power delivered to a load by rapidly switching it on and off. This technique has a wide range of applications, from simple LED dimming to more complex motor control. In this article, we’ll dive deep into the world of PWM and explore its inner workings, applications, and how you can implement it in your own projects. So, fasten your seatbelts, and let’s get started! Image Source:https://www.digikey.tw/ In this article, we will explore pulse width…

Arduino Tutorial: Control LED Brightness with PWM for Breathing Effect
In the previous Arduino tutorial, we learned how to control the on/off state of an LED. In this tutorial, we will learn how to control the brightness of an LED using Pulse Width Modulation (PWM) with Arduino. https://www.ninniku.tw/getting-started-with-arduino-lighting-up-an-led/ The LED brightness is controlled by adjusting the duty cycle of the PWM signal. The duty cycle is the ratio of the time the signal is on to the total time of one cycle. The larger the duty cycle, the brighter the LED, and vice versa. Step 1: Connect the Circuit We will keep Pin 8 as a digital control circuit, and connect it to the red LED on the circuit. Another…

Difference between Arduino and Raspberry Pi
Raspberry Pi and Arduino are both popular platforms for building electronics projects, but they have different strengths and applications. Raspberry Pi is a small single-board computer that can run a full operating system like Linux. It has more processing power and memory than Arduino and can be used for a wide range of applications, including multimedia and web applications, data processing, and machine learning. Raspberry Pi is suitable for projects that require a more powerful processor, networking, and storage capabilities. Arduino is a microcontroller board designed for building simple to complex electronics projects. It has a small memory and limited processing power compared to Raspberry Pi, but is more efficient…
