This paper aims at controlling the vehicle using speech recognition method. Vehicle is controlled through voice commands given by the end user which stops and moves in various directions such as forward, backward, right and left. The vehicle is mounted with camera and an LCD screen to view the com- mands and distance between the vehicle and the obstacles. Application works on voice commands with in a distance of 1 meter. Vehicle is attached with GPS. Vehicles can also be controlled remotely or autonomously with the help of controller and sensors. Vehicle provides signals whenever it founds obsta- cles during mobility. Vehicle moves with predefined commands

Gas leakages result in serious problems in households and other areas where household gas is used. We are using many household appliances frequently but we are not servicing all of it, we are servicing only our luxurious and costly items in regular intervals, we are not taking care of essential appliances. Gas stove is one of it, using for a long period of time in kitchen the spills of oils and water fall over the cylinder tube, they become rust and cause hole in it through which gas gets leak and can cause a fire accident. The aim of this paper is to monitor and detect the gas leakage. The sensor is fixed in the cylinder used to detect gas leakage. During working in the kitchen if the gas leakage is sensed the lcd monitor displays a alert message and gives an alarm alert. If the gas leakage is found during the absence of peoples in home, sensor sense the leakage and sends the alert message to the user mobile through an application. The status of gas leakage is fed into the controller, using wi-fi connection the wi-fi module sends the alert message to the cloud and it is redirected to the application over the internet.

Accessibility to basic healthcare is an important one in terms of development towards building a healthy future. The MEDICAL ASSISTIVE ROBOT is a device used to provide correct medication at correct time with the right amount of dosage without the aid of nurse. The robot also act as path following robot so there is no need to reach the robot in order to take the pill instead of that robot will reach the patient, it also consist of an object detecting sensor(IR) to avoid the obstacle in the path. The device uses RFID card to link the patient id which hold all the data of the patients such as identity and their prescription etc.. A specially designed wheal like structure with N number of slots acts as pill storage space. The arduino microcontroller used to automate the whole process. Each slot of pill storage named to a particular tablet in terms of rotating angle of stepper motor. Suction pump used to pick the pill. The process starts when the user taps the RFID card. In this work the device is designed and manufactured in an efficient way. There are some other devices that perform similar function Ex: The Automatic pill dispenser, All time medication but this project deals with integration of the doctors prescription, which results in overcoming the manual error. The objective of this project is to reduce the avoidable medication errors in the absence of the doctor also help the older people who are poor in memory.

This report aims to give an overview of a standalone automatic fan speed controller that controls the speed of an electric fan according to our requirement. With the help of the embedded technology makes more efficient and reliable with this closed loop feedback control system. This project is the Temperature Based Fan Speed Control & Monitoring with the help of the Arduino UNO and LM35 Temperature Sensor. In this the microcontroller controls the speed of an electric fan according to the requirement & allows faster control and the LCD display makes the system user-friendly. The LCD panel displays the Sensed temperature in Celsius Scale and fan speed in percentage simultaneously.

This paper represents the design of an Arduino based gesture controlled automated wheelchair. The design is developed with a gesture recognition system, which allows the physically disabled person to control the wheelchair by slight moment of finger who have issues in hand movement due to ageing or paralysis for joystick-controlled wheelchairs. The design also provides some additional features such as obstacle detection for the safe movement. To implement the design, Arduino Mega2560, ultra-sonic module, and motor controller circuits are used to drive the wheelchair. The designed wheelchair system does require a wearable sensor for obtaining the finger motion to control wheelchair movement (i.e. Accelerometer sensors). The proposed structure is relatively simple and cheaper that can benefit a huge population of ordinary people to have an automated wheelchair.
