The issue of obesity has become a significant public health concern, and an automatic BMI machine for outdoor use with inbuilt monitoring system can be effective solution. This project proposes low-cost that installed at places, designed using Arduino Mega Microcontroller. is activated by coin sensor provides audio-based interactive service to the user. It calculates measures parameters such as...

Microcontrollers are used in automatically and autonomously controlled products and devices, such as automobile engine control systems, implantable medical devices, remote controls, office machines, appliances, power tools, toys and other embedded systems. By reducing the size and cost compared to a design that uses a separate microprocessor, memory, and input/output devices, microcontrollers m...

Abstract This paper explains the integration process of an autonomous quadcopter platform and the design of Arduino based novel software architecture that enables the execution of advanced control laws on low-cost off-the-shelf products based frameworks. Here, quadcopter dynamics are explored through the classical nonlinear equations of motion. Next, quadcopter is designed, built and assembled ...

This article describes ARTK, a compact real-time kernel for the Arduino embedded systems development environment. It provides a priority-driven preemptive task scheduler, semaphores for task synchronisation, and serial channel output. It is compatible with Arduino boards containing more or less than 64 kbytes of memory. The memory footprint of ARTK is under 8 kbytes.

In this work a low cost Arduino based Bridge health monitoring system is proposed. This uses Web Server with IP connectivity for accessing accelerometer readings. Statistical signal processing of readings obtained from sensors involve intensive calculations. As a result processors that support large data size and high duty cycles are required for data assessment. Internet of things (IoT) helps ...

Arduino is a popular open source hardware toolkit for science and engineering education due to its easy use and various good examples. But, students or beginners who have no experience and knowledge of electronic engineering or programming languages still feel a considerable barrier to use Arduino. This study analyzes the barrier of beginners in using the open source hardware. In order to resol...

Languages such as High Performance Fortran are used to implement parallel algorithms by distributing large data structures across a multicomputer system. To hide communication behind computation, we introduce an optimization scheme, message strip-mining. By using this scheme, the communication overhead is almost completely overlapped with the subsequent computation. We have implemented the prop...

In the last fifteen years, the technological education has been essentially based on digital technology, leaving aside the use of concrete material. Still having excellent simulators of the physical world, working with concrete material allows the development of cognitive structures that digital doesn't offer. Moreover, these didactic resources allow highly participative group dynamics that hav...

This paper presents design and practical implementation of single-phase inverter based on selective harmonic elimination-pulse width modulation (SHE-PWM) technique. Microcontroller mega type Arduino used as a controller for producing the gate pulses. The optimized switching angles determination results in wide range output voltage. Depending number angles, lower order harmonics (LOHs) can be el...
