Gearbest review: Arduino Mega2560 and LCD keypad demo project

Arduino is an excellent platform for fast prototyping and building projects. But probably one of the best things here is that Arduino layout allows plugging hundreds of standard shields. Today you can probably find any type of sensor, displays, driver included in to shields. This is where comes the real power of using Arduino. Gearbest have supplied us with a great combination of commonly available products, including Arduino Mega2560 and LCD keypad shield. Arduino Mega2560 comes with powerful AVR ATmega2560 microcontroller featuring 54 I/Os, 256KB flash, 4KB of SRAM, and 4KB of EEPROM. It has standard Arduino header layout extended with tens of additional that are not occupied by shields. They can be successfully used with additional gear.

II Introduction and background Today, the problem of environmental protection is one of the major challenges to contemporary society. In actuality, this problem is global and affects the entire global community. In such a situation, the ineffective use of technology and excessive energy consumption by buildings, both households and public or private buildings used for other purposes, contributes consistently to the aggravation of environmental pollution. Traditionally, technologies, including information technologies, have been viewed as the major source and driver of energy consumption growth. To a significant extent, such a view on the technology was right because the technology’s progress stimulated the wider use of new devices, machines and equipment that required more and more energy. At the same time,…

Working In Medicine (Without Being A Nurse)

Many people who want to jump into the healthcare profession are not particularly interested in nursing, where the work can be backbreaking, very dramatic or very dull. It can also involve internal medicine, which may not be your cup of tea. So, what do you do? If you’re looking for rewarding work, but don’t really care for the sight of blood or have worries about the heavy lifting involved in nursing, try these technical job ideas out for size. After all, income levels for peripheral healthcare technicians, such as radiation therapist or sonogram technician, are holding up well, because of the high demand training. Here are some job ideas for smart folks who don’t necessarily care for a traditional job as a nurse or a doctor:

Accessing AVR microcontroller ports with AVR GCC

All AVR ports have Read-modify-write functionality when used for general I/O functionality. The direction of each separate port pin can be changed. Each pin buffer has the symmetric capability with the ability to drive and sink source. The pin driver is strong enough to drive LED directly, but it is not recommended to drive even small loads without using proper driver circuit such as transistors. All port pins have internal selectable pull-up resistors. And finally, all pins have protection diodes to both VCC and GND rails. Each port of AVR consists of three registers DDRx, PORTx, and PINx (where x means port letter). DDRx register selects the direction of port pins. If logic one is written to DDRx then the port is configured to be as output. Zero means that the port is configured as an input. If DDRx is written zero and PORTx is written logic “1” then the port is configured as input with an internal pull-up resistor. Otherwise, if PORTx is written to zero, then the port is configured as input, but pins are set to tri-state, and you might need to connect external pull-up resistors. If PORTx is written to logic “1” and DDRx is set…

Guide For Modern Electrical Safety

Most people understand the potential hazards of working with electricity, yet many men and women face those risks every day. Jobs in engineering, maintenance, and construction represent just a fraction of those workers who must handle some electricity. Even office workers who don’t directly handle electricity may come into contact with electrical hazards at times. Fortunately, the standards for safety, which are provided in courses of safety and electrical training, have increased our comfort with electricity. Today, because of these standards, most people don’t give a second thought to the electricity flowing through their homes, businesses, and places of recreation. On-Going Education To maintain the safety standards and our comfort around electricity, professionals in any field of electricity must remain up-to-date with all current information. Anyone who works with electricity must understand advances made about electrical safety. Some of these areas include: Protective devices Power generation, transmission, and distribution The use of electric systems Wiring safety Increased safeguards for personnel protection The United States Department of Labor provides updates on OSHA requirements. Participation in regular training courses is an effective way to improve and maintain high levels of safety.

Features of classrooms Automated by Linear Actuators

Various features are used to identify the classrooms that have been automated by linear actuation. These features make it easy and simple to ensure that the classrooms are automated. The automated classrooms using the linear actuators are comprised of a single interface that is used in controlling all the equipment in the classroom. This paper will look at the features of the classrooms that are automated using the 12-24 volt linear actuators. The automated classrooms using the linear actuators are comprised of projectors, cameras, computers, speakers, and various equipment used to control the various elements of nature. This includes the regulation of temperature and the intensity of light in the classrooms. The linear actuators are linked to form complex systems that are controlled from one interface. This makes it possible for the students and the instructor to conveniently control the equipment to ensure that they acquire more from the lessons. Some other features associated with the actuators include the automatic opening and closing of doors, moving the tables and chairs, and the camera surveillance for the classroom.

How to drive stepper motor with Arduino motor shield

driwing stepper motor with arduino motor shield

Previously we have driven servo and DC motor using an Arduino motor shield. It is easy to interface with these motors and write the code. This time we get to the stepper motor control and discover the full potential of the motor shield. Stepper motors are more complex devices than servos or DC and require some knowledge before running them. You cannot expect to plug some voltage and see it spinning. Their primary purpose is precise stepping that gives control of how much the motor is turning. You can find a stepper motor in any printer which feeds paper incrementally – and this is where you can get one. Disk drives are another great source to scavenge. We will not get into stepper motor working theory. Do your research before trying to run one.

Why Using Ruby on Rails

Nowadays, many big and small companies prefer using Ruby on Rails when creating applications that are to be delivered on the web. It is not surprising, as Ruby on Rails offers lots of advantages over other web development frameworks. Lets have a closer look at the benefits of Ruby on Rails or Ruby, as it is usually called. This framework’s main advantage is that it makes the life of a web developer easier by allowing writing less code, which is achievable due to a leaner code base. Ruby on Rails is very easy to use. Besides, it gives speed and flexibility that no other scripting language or framework can give. Creating websites with Ruby on Rails is a lot faster and easier than with other web developing solutions. Generally, to develop and launch a website, the developer needs about twelve weeks. While using Ruby on Rails, a web developer needs six weeks to complete a similar project. The modular design of Ruby on Rails allows reusing earlier created elements rather than creating new ones. Making changes and adjustments is also a lot easier if a site is created with Ruby on Rails.
