MOVI voice recognition control shield Arduino

It could be a challenge for makers who are incorporating voice commands into Arduino projects, but now, MOVI, an speech recognizer shield for Arduino projects, can make this task straightforward with its full sentence capability. Now, let’s be more familiar with it!

MOVI, standing for My Own Voice Interface, is the first standalone speech recognizer and voice synthesizer that adds voice control functionality with full English sentence capability to any Arduino project.

 

MOVI is a true Arduino shield with many interesting features. It is single board off-line speech recognizer and voice synthesizer using a 2GB on-board database of up to 200 customizable sentences to recognize what a user is saying. As an off-grid solution that do not connect to the Internet, it also ensures user privacy.

Besides, it is very easy to program with a programmable call sign and versatile programming interface. It provides an alternative to buttons, remote controls, or cell phones by letting you use full-sentence voice commands for tasks such as turning devices on and off, entering alarm codes, and carrying on programmed conversations with projects.

MOVI is plug and play! Connect the shield to your Arduino Uno or compatible board, connect an optional speaker, and you’re ready to go. It is cloudless and does not require Internet connection or an external PC. All of the processing is done on its 1GHz ARM-based processor.

In a word, MOVI is doing away with all the limitations of other shields by offering a true state of the art speech recognizer that can be trained to recognize hundreds of English sentences. With MOVI, makers will be able to complete their Arduino projects straightforward!

Differences between Wifi shield and YUN shield

Some users may not sure of the difference between the wifi shield and Yun shield. Actually, there are some similar features with both shields, but there are also some differences, you can read the following introduction and will know the differences:

This WiFi Shield connects your Arduino or Crowduino to the internet wireless. Just connect it to your wireless network with a few simple instructions, you can start to control your applications through the internet now. This Wifi Shield utilizes a RN171 which is a complete, standalone TCP/IP wireless network module, to provides your Arduino/Crowduino internet connectivity via 2-pin serial port. Also, on the board there is an on-board micro SD slot ready for your store your data, making you applications such as weather monitoring easily!

You can make much more applications now, such as the smart home networks, robot controls or personal weather stations, etc. Also, a basic Arduino library is ready for you to help to enter the world of Arduino Wifi!


Yun Shield is designed to solve the Internet connectivity and storage issue for Arduino Board. Alike the Arduino Yun, it provides a Linux system, WiFi, Ethernet to the Arduino board for connectivity. Yun Shield runs Open Source OpenWrt system (Same system as runs in Arduino Yun) and it is fully compatible with Arduino IDE v1.5.4 or later.

Yun Shield is the ideally choice for Arduino Projects which require various internet connections and more storage. Basically, Yun Shield + Leonardo equally to the official Arduino Yun, but Yun Shield is more flexible because it can work with other Arduino board such as Uno, Duemilanove, Mega etc. And Yun Shield uses external wifi antenna which provides stability and possibility for various environments.

Benefits of buying a New generation 2 Wheel Self Balancing Electric Scooter

More and more people would like to take 2 Wheel Self Balancing Electric Scooter when going to work or to other places. It could be a good phenomena to see that cause the 2 Wheel Self Balancing ElectricScooter can be environment-friendly and save energy without oil consumption. But for most people, 2 Wheel Self Balancing Electric Scooter can be a new things as seldom people use them as a transport tool.

Knowing more info about it can bring a faster and wider use of this tool. Here you can know the benefit of owning a 2 Wheel Self Balancing Electric Scooter.

Competitive Advantage. There are 7 Colors for your choice. Customized colors are accepted Without MOQ Requirements. Besides, it can be auto electricity off when fall down and it can offer you emergency protection when lose control! You can handle bar can be adjustable according to your height and it has digital Battery status display and tubeless Off-road Wide tire.

The most important, it can offer you high efficiency. It utilize circular energy reserving system is another sparkle of V5+. By utilizing the control module of gravity, V5+ can brake and stop by judging the center of gravity rather than configuring a traditional brake system based on friction. And as a result, during the process of deceleration, kinetic energy converts to electric energy being stored in the battery without losing any heat energy due to friction. In a word, there is no energy waste.

As for the power supply, V5+ is an ideal and advanced travel tool in an extremely crowded city because of its small size, reliable security and unique driving technology. The innovation of its structure design is based on the principle that A little body often harbors a great soul. With the fast development of modern metropolis, V5+ is now being accepted as a superb solution for individual traveling.

What’s more, taking a 2 Wheel Self Balancing Electric Scooter, it can be zero emission and no pollution. All the power source of Wind Rover V5+ comes from lead acid battery, and it is convenient to charge by using power supply for household. You can enjoy driving about 35-40km at the speed of 10km/h-25km/h after charging, without any emission or any destruction to the environment.

Besides, it can help you to save more money as it is low energy consumption. Wind Rover V5 has an extremely low cost_0.02/km per person, 30 times less than the cost of a car with displacement 1.2L, which is 0.68/km per person. It also saves more energy than electric vehicles because the mass of V5 is only about 18kg whereas the weight of a traditional electric vehicle is more than 1 ton, which leads to more energy consumption due to its dead weight.

Anyway, you can also have a try if you are tied of cramming onto a bus or driving your own car. And you don’t need to worry about the consumption and you can save a lot of money. Besides, you can have a look at 2-Wheel Self-balancing Robot from Elecrow. If you have spare time, you can have a try to make one all by yourself. It is quite interesting and useful in daily life. Why not have a try? 

Benefits of taking a global positioning system from GPS shield with you

The world is so big, I want to see!! Most people would like to go traveling around. But as it’s known to all that most people especially the girls are direction idiots that have no sense of direction when they are outside. That could be a difficulty for those who want to go travelling. Luckily, people can reach a GPS from GPS shield with them so that they can find the direction and place quicker and improve the accuracy at the same time. With the GPS, you can go anywhere you want to.

Global Positioning System is a navigational aid and a GPS can be of great help in finding the direction and what are other benefits of a GPS and what’s the main material of it? The GPS shield has a GPS antenna connected. This is very important as you can't get a location fix if you don't have an antenna. Actually. You can also DIY GPS if you have spare time, it is quite easy. First you should set the voltage switch on your GPS shield to 5v before you power it on and connect it up. There is also a 3.3v setting.

Next you need to set the jumpers for Rx (receive) and Tx (transmit) on the GPS shield. You can set the GPS Rx to pin 6 and GPS Tx to pin 5. If you want to receive the output of this circuit on computer, you needed the default hardware serial interface for that. To communicate with the GPS shield, use the mega hardware serial interface. If used outside with a clear view of the sky it will get a GPS fix even faster.
