How to Create Air Gap in a Ferrite Core Transformer
In this article we are going to understand in detail how we can create air gap in a ferrite core based transformer which we are using in smps circuits like flyback or boost or forward type. Introduction We must understand that ferrite cores have very high permeability and they saturate very fast if we do […]
GSM Car Ignition and Central Lock Circuit Using Arduino
In this post I will show how to construct a GSM based car security system using Arduino, which can lock and unlock car’s ignition system and central lock by sending a password SMS to car from your cellphone Car theft can be a heart break; it feels like your loved one got kidnapped. It hurts […]
Line Follower Robot Circuit using Arduino
In this post I have explained how to build a line follower robot circuit using Arduino, which will run over a specifically drawn line layout and will faithfully follow it as long as it is available and traceable by its sensors. By Navneet Sajwan What is a Line Follower Robot An autonomous robot is a machine […]
Automatic Irrigation Circuit using Arduino
In this post I will show how to construct an automated water irrigation system for small garden using arduino and soil moisture sensor. Introduction The proposed system can monitor the soil moisture level and when soil moisture goes below preset value, the 12V DC pump will be triggered for predetermined period of time. The status […]
Arduino Digital Clock Using RTC Module
In this post I will show how to construct a digital clock using RTC or Real Time Clock module. We will understand what “RTC” module is, how to interface with Arduino and what it does. RTC module is a circuit, which keeps track of current time accurately. It does two functions, it communicates with microcontrollers […]
