Control Electrical Devices Anywhere In the World Using Raspberry Pi

Abstract: Automation or automatic control means the use of various control systems for operating equipment. Home automation is exciting field when it is blow up with new technologies like the Internet of Things(IoT). It is automation of the home, housework or household activity. The main advantage of this is small device can be part of internet so it is easy to communicate, manage and control without human interferences. Also it provides high degree of security, safety, comfort and energy saving. With the arrival of Raspberry Pi which is small, inexpensive, portable credit-size single board computer with support for a large number of peripherals and network communication like Ethernet port, USB port, HDMI port, SD card slot. Raspberry pi set of technologies now exist that combine the power of PC, communication and multimedia technologies of web and portability of mobile device.

IOT BASED LIVE VIDEO STREAMING ROBOTIC CONTROL SYSTEM USING RASPBERRY PI

In the present world, everyone is worried about their safety due to increase in crime rate. This has led to an increase in the importance of a surveillance system. A system is designed for continuous monitoring and also the system provides live streaming. The system can be deployed at the anyplace i.e. office, house and some remote place where people cannot monitor the particular place. The system acts like a Robot within a local area network through Wi-Fi technology using Raspberry pi 3 model. The live streaming is accomplished by using a webcam interfaced with Raspberry Pi, it data provided is processed by MJPEG (Motion Joint Photographic Experts Group) streamer and the robot is controlled through webpage’s created. The system is programmed using python programming language.

INTRODUCTION:


As the growth rate of crime has been increased in past years, as a result, everyone is concerned about their safety and security. Due to this reason, people started to consider the significance of surveillance systems. The majority of the people are doing Internet Protocol (IP) based installations rather than analog
because of IP-based installations are from anywhere. In order to make the IP-based systems affordable for the people having a low budget, we need to develop a system which is cost effective and portable. This paper describes the system which acts as a robot.This robot uses raspberry pi model „B‟ for making this
real-time surveillance possible by providing the installing and processing high resource software's which makes it possible to live streaming & controlling the robot.

Raspberry Pi Based Home Automation Using IOT with Python GUI

Controlling A Robotic Car Through MATLAB GUI

This project presents the implementation of a MATLAB based graphical user interface (GUI) to control the movement of a robotic car. The commands to move the car in forward, reverse, right and left directions are sent from the GUI and processed by Arduino Uno board mounted on top of the car.



In this project, MATLAB based GUI communicates with Arduino through a USB data cable. You can send commands to Arduino to move the car in a specific direction by pressing the corresponding push button in the GUI. The particular push button, when pressed, executes callback function corresponding to that push button in the MATLAB program, car.m. Within that function, instructions to set/reset the digital I/O pins (8, 9, 10 and 11) of Arduino are executed to drive the car in the desired direction.

ARDUINO BASED DEVICE CONTROL SYSTEM USING MATLAB

In present time home office appliance controlling is a common thing.  Today for controlling home/offices appliances, machinery in companies/industries uses different types of automation systems like DTMF controlled, GSM controlled and many others. So here this project is made for interfacing MATLAB (Graphic User Interfacing) and Home/office/industries automation using Arduino and MATLAB.

Here MATLAB is interfaced with Arduino through serial communication. In this Arduino is burned with an ARDUINO IO (Also Known As: "TETHERED" MATLAB SUPPORT PACKAGE FOR ARDUINO). This package allows using an Arduino connected to the computer to perform Analog and Digital Input and Output, (and command motors) from MATLAB.

Circuit Description: Circuit of this home automation system is very simple. Digital Pin number 10 of Arduino Pro Mini is directly connected to LED used as a light lamp and small fan used as selling is connected to pin number 11 of Arduino and ground of both appliances connected to Arduino ground.  And Arduino is connected to the computer over serial communication. Here I used FTDI burner for serial communication.
The programming part of this system is also very easy. There are two program files for this project one for Arduino and second for MATLAB. Arduino MATLAB program file is easily available on the internet. And MATLAB program you can build. Before programming, you have to make a user graphic interface (GUI) window in MATLAB. This GUI automatically creates a program file. Now you can write the program as you wish. But here I have programmed for LED and Fan only.
