Why Arduino and WiFi together is the Future you were promised

The Arduino revolution recently turned to the basis of most rapid prototyping projects. Hard to believe it’s been ten years since that little blue board of electronics magic found its way out of Italy and onto lab benches around the globe. Most of you who are reading this must have hard an experience with the Arduino uno, it was most probably the first prototyping platform you came across. Now imagine that coupled with Wi-Fi on board? There is already a new board that is Wi-Fi capable, which Arduino hopes will encourage people to use the boards to make cloud-ready projects.

Currently, Arduino series of boards provides different options for connectivity and power management, encouraging people to use them as one standard format for IoT projects. MKR boards can bring more standardization to the design process, making the designer’s life easier when trying to sell a final product in the market that’s because many designers/makers will likely use this same format for their IoT projects.

Internet of Things is a recent technology that creates a global network of machines and devices that are capable of communicating and exchanging data with each other through the Internet. There is a difference between the Internet of Things and the Internet. Internet of Things can create information about the connected objects, analyze it, and make decisions; in other words, one can tell that the Internet of Things is smarter than the Internet. Security cameras, sensors, vehicles, buildings, and software are examples of things that can exchange data among each other.


The Arduino Uno WiFi Rev 2,is based on the new Microchip Technology ATmega4809 megaAVR microcontroller. The ATmega4809 offers Core Independent Peripherals (CIPs) and an integrated high-speed analog-to-digital converter (ADC) with voltage reference for faster conversion of analog signals. The microcontroller also provides more memory than on previous Uno boards, boasting 48 kBytes of flash and 6 kBytes of RAM, plus three UARTs to enable communication with more than one RF module. The Uno WiFi Rev 2 includes a u-blox NINA-W13 module with integrated TCP/IP protocol stack to provide 802.11b/g/n Wi-Fi connectivity enabling access to a Wi-Fi network or for use as an access point. The board also features support for over-the-air (OTA) programming for transfer of Arduino sketches or Wi-Fi firmware. Wireless security is provided by a Microchip ECC608 CryptoAuthentication IC, which combines hardware-based key storage with hardware cryptographic accelerators to implement authentication and encryption protocols. Other features include onboard debugging, inertial measurement unit (IMU) with 3-axis accelerometer and 3-axis gyroscope, 14 digital input/output pins (six PWM outputs), and six analogue inputs.
