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 […]

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 […]
Over Current Cut-off Power Supply Using Arduino
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. By Girish Radhakrishanan Main Technical Features The proposed over current cut-off power supply circuit using Arduino has 16 X 2 LCD […]
Make this Advanced Digital Ammeter using Arduino
In this post I will show how to construct a digital ammeter using 16 x 2 LCD display and Arduino. We will understand the methodology of measuring current using a shunt resistor and implement a design based on Arduino. The proposed digital ammeter can measure current ranging from 0 to 2 Ampere (absolute maximum) with […]
Using Digital Potentiometer MCP41xx With Arduino
In this project we are going to interface a digital potentiometer with arduino. In this demonstration potentiometer MCP41010 is used but you can use any digital potentiometer of MC41** series. By Ankit Negi INTRODUCTION TO MC41010 Digital potentiometers are just like any analog potentiometer with three terminals with only one difference. Whereas in analog one […]
How to Control Servo Motor Using Joystick
In this post I have explained how to control servo motors using a joystick and Arduino. We will see overview about joystick, its pins, its construction and working. We will be extracting useful data from the joy stick which will be base for controlling the servo motors. Introduction The motto of this article is not […]
