Wireless Control of Devices with the Arduino MKR1010

Arduino LiveCast demo how to control an Arduino MKR1010 from a cell phone, via WiFi.

Introducing the Arduino MKR WiFi 1010

The MKR WiFi 1010, which offers low power consumption and has been designed not only to speed up and simplify the prototyping of WiFi-based IoT applications, but also to be embedded in production IoT applications that require WiFi connectivity. The board is an evolution of the existing Arduino MKR1000, but now comes equipped with an ESP32-based module manufactured by u-blox. This key element delivers 2.4GHz WiFi and Bluetooth communications capability, along with leading RF and power performance: the ESP32 is a highly flexible device that provides adjustable power output, enabling optimal trade-offs between communication range, data rate and power consumption.

Fully compatible with the Arduino IT cloud, the MKR1010 also offers simple migration from other Arduino boards, and uses open-source WiFi firmware, which makes it easy to reprogram for upgrading or to repair any security flaws. A significant feature is the MKR1010’s two standalone programmable processors – the first based on ARM processor core technology, the second based on a dual-core Espressif IC – making the board a high-performance solution that can distribute its workload across its dual-processor system. Another major feature is the integration of a secure authentication module – Microchip’s ECC508 – which uses crypto authentication to secure TLS network communications and connections.

DIY Weather Station & WiFi Sensor Station || ESP8266, Nextion LCD

DIY Weather Station & WiFi Sensor Station || ESP8266, Nextion LCD

It's a great video show you how to create a weather station along with a WiFi sensor station. The sensor station measures local temperature and humidity data and sends it, through WiFi, to the weather station. The weather station then displays the data on its LCD screen. It also grabs the current temperature and humidity data in your city from the Internet and displays it as well on the LCD screen.
