Ar Project

AC Voltmeter using Arduino In this project, we are going to make an  AC Voltage Measuring Device using Arduino,  which will measure the voltage of Alternating Current Supply at our home.  We are going to print that voltage on serial monitor of Arduino IDE as well as show on the multimeter. Making a Digital Voltmeter is a lot easy than making an analog one because in case of analog voltmeter you must have good knowledge of physical parameters like torque, friction losses etc. whereas in case of digital voltmeter you can just use a LCD or LED matrix or even your laptop (as in this case) to print the voltage values for you. Here are some  Digital Voltmeter Projects : Simple Digital Voltmeter Circuit with PCB using ICL7107 LM3914 Voltmeter Circuit 0-25V Digital Voltmeter using AVR Microcontroller Required Components: One 12-0-12 transformer    1N4007 diode    1uf capacitor    Resistors 10k; 4.7k.    ...

Automatic Call answering Machine using Arduino and GSM module In today’s modern world we all depend on mobile phones as our primary means of wireless communication. But, we all have faced situations during which we might not be able to answer to our calls, these calls might be an important personal call or a life changing business call and you could have just missed that opportunity since you were not able to answer that call at that particular time. This project aims to solve this problem by creating an  Automatic Call answering Machine by using Arduino and GSM module . Next time when you are changing to a new phone number or out for a long pilgrimage trip or enjoying a well deserved vacation just use this machine to record your voice stating the reason for absence and all your calls will be automatically answered by this machine and your recorded voice will be played to them. This can also be used for your business numbers to answer to your customer’s calls duri...

Control your Computer with Hand Gestures using Arduino Recently  Gesture controlled Laptops or computers  are getting very famous. This technique is called  Leap motion  which enables us to control certain functions on our computer/Laptop by simply waving our hand in front of it. It is very cool and fun to do it, but these laptops are really priced very high. So in this project let us try building our own  Gesture control Laptop/Computer by combining the Power of Arduino and Python . We will use two  Ultrasonic sensors  to determine the position of our hand and  control a media player (VLC) based on the position . I have used this for demonstration, but once you have understood the project, you can do anything by just changing few lines of code and control your favorite application in your favorite way. Pre-requisites: We have already covered few projects which combines Arduino with Python. So I assume that you have already inst...
