In this post I will show how to construct a battery eliminator / DC variable power supply which will automatically cut-off the supply, if the current flow through the load exceeds the preset threshold level. Main Technical Features The proposed over current cut-off power supply circuit using Arduino has 16 X 2 LCD display, which is […]

How To Use And Program ATmega Microcontrollers From Scratch Without Arduino
ATmega microcontrollers, they are coming from the AVR family which Atmel developed long back, and later this Atmel company was taken by Microchip. So now officially Microchip owns it but still people say Atmel AVR only. These MCUs became very popular slowly because they are easy to understand, quite affordable, stable in long run and […]
8 Channel Lighting Sequence Generator Circuit for Christmas, Diwali Decoration
In this post I will explain how to make one full adjustable lighting sequence generator which can control and illuminate many external bulbs through triacs in many different running patterns. We can make it so that user can change and select any sequence pattern easily. We will use Arduino for the full control part. Let […]
Introduction to EEPROM in Arduino
In this post I have explained what EEPROM is, how data is stored on built in EEPROM on Arduino board’s Microcontroller and also practically test how to write and read data on EEPROM by a couple of examples. Why EEPROM? Before we ask what EEPROM is? It is very important to know why EEPROM […]
Mobile Phone Controlled Robot Car Using DTMF Module
In this project we are going to control a manual robot through our cellphone using DTMF module and Arduino. By: Ankit Negi, Kanishk Godiyal and Navneet Singh sajwan INTRODUCTION In this project two cell phones, one for calling and one for receiving the call are used. The phone receiving the call is connected to the robot […]
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 […]
