PCB Manufacturing Simplified by JLCPCB

Ligo George — Tue, 07 Sep 2021 02:14:10 +0000

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 […]

Interfacing Relay with Arduino Uno

Rani Chowdary — Tue, 18 May 2021 05:59:07 +0000

In this tutorial, we are going to interface a 5V Relay module with Arduino Uno to control high power devices. As you might already know, Arduino Uno work on 5V and the maximum current a digital pin can drive is less than 40mA. So technically we cannot drive higher power devices like home appliances DIRECTLY […]

Remote Debugging of Embedded Systems

Ligo George — Wed, 28 Oct 2020 04:47:10 +0000

Most of us are working from home during this COVID-19 pandemic situation. I have personally struggled to debug some of my hardwares remotely. Today I am going to introduce a completely new method for remote debugging of embedded systems. Using this method you can debug a remote system as if it is connected to your […]

Interfacing L298N Motor Driver with Arduino Uno

Rani Chowdary — Thu, 21 May 2020 02:59:32 +0000

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 […]

Interfacing Mercury Tilt Switch with Arduino Uno

Rani Chowdary — Sun, 10 May 2020 14:34:58 +0000

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. […]
