Underground Cable Fault Detector Using Arduino

underground fault location model using arduino. Underground distribution cables faces with various technical difficulties regarding detecting and locating their faults. Different factors like remarkable charging currents, cable construction and variations from the variety of bonding and grounding methodologies. Arduino is basically an open source hardware used to create interactive electronic objects consisting of various analog and digital pins, serial communication interfaces, including USB on some models, for loading programs (c++, c, and java) from personal computers. The LCD (liquid crystal display) used is of 16*2 displays. In this paper, concept of ohm’s law is used. To detect a fault in the cable, the cable must first be tested for faults. When any fault like short-circuit occurs, voltage drop will vary depending on the length of fault in cable, since the current varies. A set of resistors are therefore used representing cable length in kilo meters and fault creation is made by a set of switches at every known kilo meters (km’s) to cross-check the accuracy . The fault occurring at what distance and which phase is displayed on a lcd interfaced with the arduino. The underground cable system is especially used for distribution in metropolitan cities, airports and defense service, because underground cables are not affected by any adverse weather conditions.

Refreshable Braille Display using Raspberry Pi and Arduino

The aim of this project is to create a refreshable electronic braille display using Raspberry Pi 2 and Arduino Mega2560 board. This aims at creating a refreshable braille display that is capable of converting Normal text file as well as printed image files to braille. To achieve the functionality of converting image files to text we have used tesseract-ocr engine of Google which the best available OCR engine available right now and is highly accurate. The Raspberry pi does the image processing and the Arduino drives the display. The display is made of 6 servo motors, which can be controlled by the PWM. The servo motor acts as an actuator in this project..

Overcurrent Protection of Transformer by incorporating IDMT function with the help of Arduino Uno Microcontroller

Power transformer is an important and vital part of the electrical power system, there protection and continuous monitoring is very crucial for an uninterrupted power supply. There are various types of relays available for protection of transformer, one of the relay commonly known is IDMT relay. IDMT relays usually uses eddy current effect for attaining inverse definite minimum time (IDMT) relation but by using a microcontroller instead, will give relay more appropriate operation and better time response. Here in this paper IDMT scheme is applied to the relay through microcontroller. A current sensor is also developed which will give DC output voltage in proportion to increasing load current and the same voltage levels are being used for programming

TCP/IP Remote Communication for Arduino based Motion Control using Virtual Instrumentation

Describing with several methods to achieve of remote data acquisition based on LabVIEW, introduced the design method in the LabVIEW platform, combined with Aurduino and TCP / IP protocol for data acquisition and transmission of the long-range ,and realization of the signal on the time-domain analysis and on the frequency-domain Analysis. Two computers running LabVIEW at the same time, real-time data send and receive between computers by the interface of Virtual Instrument, which can realize multi-machine data transmission and reading, in order to complete remote data sharing and controlling. LabVIEW platform provides a support for remote controlling and the monitoring of equipment. Proposed system is aimed at design and development of remote laboratory activities monitoring and controlling system for motion control using h-infinity algorithm.

Arduino Based Smart Drip Irrigation System Using Internet of Things

Nowadays water scarcity is a big concern for farming. This project helps the farmers to irrigate the farmland in an efficient manner with automated irrigation system based on soil humidity. Humidity sensor is used to find the soil humidity and based on this microcontroller drives the solenoid valve. Irrigation status is updated to the server or localhost using Personal Computer. Java platform is used here for getting information via serial communication from microcontroller and to update in the server. In addition for better cropping system, fertilizers required for the crops, best crops to cultivate for the particular climatic and soil conditions are updated to server at regular basis by monitoring soil PH level, Temperature level of the field area etc., By using PC host, crop is continuously monitored. Also LCD is used to display the PH, temperature and moisture level. This will improve the cultivation method and leads to better productivity

Juniper: A Functional Reactive Programming Language for the Arduino

s the design and implementation of Juniper: a functional reactive programming language (FRP) targeting the Arduino and related microcontroller systems. Juniper provides a number of high level features, including parametric polymorphic functions, anonymous functions, automatic memory management, and immutable data structures. Also included is a standard library which offers many useful FRP signal processing functions. Juniper is translated to standard C++ and compiled with the existing Arduino development tools, allowing Juniper programs to fit on resource-constrained devices, and enabling seamless interoperability with existing C++ libraries for these devices.
