PCB Designing: 20 Essential Tips for Success

Creating a printed circuit board (PCB) is like building the brain of your electronic gadgets. To help you design a functional and reliable PCB, here are twenty important things you should keep in mind, explained in simple terms: Placing Components in the Right Spots: Think of your PCB like a puzzle. Each electronic part, called a component, has its own special place on the board. Just as you wouldn't mix up puzzle pieces, don't mix up your components. Proper placement ensures...

PCB Prototyping Simplified by PCBWay

Join me as I recount a personal journey that completely revolutionized my electronics engineering experience. At the outset of my ventures in the world of electronics, crafting PCBs proved to be an arduous and time-consuming task, putting my patience to the test with toner transfer methods and the complexities of local manufacturing. However, the challenges didn't stop there; I constantly found myself racing against time to procure elusive components, leading to frustrating delays in my projects. While there were various tools...

PCB Manufacturing Simplified by JLCPCB

During the beginning of my electronics engineering journey I used to make PCBs at home using toner transfer method. Later I used to do screen printing and also manufacture PCBs locally. Then I used to assemble components myself. In all these methods PCB manufacturing itself is a time consuming process. Sometimes some components won't be readily available in the market which will further take more time to arrange. Recently I have come across

L298N Motor Driver Module

Interfacing L298N Motor Driver with Arduino Uno

In this tutorial we will learn how to interface L298N motror driver with Arduino Uno. You might be thinking why we need L298N for controlling a motor. The answer is very simple, Arduino board or a microcontroller IO pins don't have enough current/voltage driving capability to drive a motor. For driving the motor in both directions (clockwise and anti-clockwise) we need to use an H-Bridge. Please read our article H-Bridge - DC Motor Driving for more...

Tilt Sensor

Interfacing Mercury Tilt Switch with Arduino Uno

In this tutorial we will learn how to interface Tilt Sensor with Arduino Uno. As the name suggests, it is an electronic device used to detect the orientation or tilting of an object and provides digital output based on the orientation. It behaves like a normal ON - OFF switch that is controlled by tilting. Tilt sensor consists of a mercury ball and two contacts in a sealed enclosure, in which the mercury ball will short the leads based on...
