Connected boards like Arduino and Raspberry have a microcontroller programmable with C ++, Java, Javascript, Python and other programming languages. These cards are equipped with input-output ports presenting a means of connection to a receiver (light sensor, sound sensor, humidity sensor, etc.) and actuators (motor, LED, display, beeper, etc.). These input outputs can be defined as analog or digital. The analog inputs / outputs can send / receive a digital signal (0 or 1) or an analog signal (variable between 0 and the maximum capacity) Example : You can send a digital signal to an LED: 1 to turn on the LED and 0 if you want the opposite.

You can also send an analog signal: the brightness of the LED will vary according to the values ​​received. For this tutorial we have chosen the Czech Republic Cell Phone Numbers List Arduino 101 board, also called Genuino, which already includes BLE. It is possible to use other Arduino boards that do not integrate BLE, but in this case, the board must be connected to an HC-05 or HC-06 Bluetooth module. BLE: Bluetooth Low Energy GIwMg Bluetooth is a wireless communication protocol. It came into being in the late 1990s and began to be successful in the 2000s. The Bluetooth protocol is a similar to Wi-Fi .

Getting Started With Intel’s Iot Gateway

Indeed, they both respect the same IEEE specification and use the same frequency range: 2.4 GHz: Communication in Bluetooth is bidirectional: two modules can communicate together at the same time. The behavior used is “master / slave”. A slave can talk with a single master , but a master can talk to several slaves . Bluetooth Low Energy is an alternative to traditional Bluetooth , with a reduction in cost and power consumption, while maintaining an equivalent communication range. Hardware: Arduino 101 or Genuino Android or iOS smartphone or tablet Software: The free nFR Master Control Panel (BLE) app on Android or iOS. Arduino IDE Bookstores: In the Arduino IDE, you must import CurieBLE.

h in order to access the parameters and functions corresponding to the operation of the BLE module on the board. With BLE it is possible to establish a connection with the application on the smartphone which will allow the control of the LED. Steps : Install the nRF Master Control Panel (BLE) app for Android and iOS Install Arduino IDE Connect the Arduino board to the PC using the USB cable Copy and then upload the code to the card Open the nRF Master Control Panel (BLE) application Scan then choose the “LED” device by pressing the “connect” button Choose the service with the ID: 19B10000-E8F2-537E-4F6C-D104768A1214 Select the option that allows access to the service in read and write Insert a value of type UIINT 8 (0 or 1) Once the value has been modified when the “Send” button is pressed.

the value is sent via BLE to the card and the LED lights up according to the value entered. Who says mobile application, says smartphone. So what does this have to do with mobile first? This expression originated in 2011 in the work of the same name written by Luke Wroblewski. This concept, which has become a reality, means that in its strategy for digitizing its business, it is now necessary to prioritize the mobile version. In November 2016, Google announced its “mobile first index” project. But what is it, then ? This index aims to rank websites according to how Google crawled the mobile version rather than the desktop version.

Before the appearance of this index, Google favored browsing first from Desktop then to mobiles. It is now the other way around. Mobile-first Therefore, this means that if you were well placed in the Google search results with your website but your mobile version was passable it did not influence your appearance in the search results, which in 2018 gradually will not be anymore. the case. squirrel-2877609_640 (Come on, don’t look at us like that, it shook us too!) The search engine realized that it made more sense to favor mobile users and provide them with the best search results and the best possible user experience in terms of content.
