MCU with built in WiFi

Microcontroller (MCU) with built in WiFi, the IoT is subject about connecting devices to the internet so that they can send/receive data, accept commands remotely through web pages or cloud applications. For example, one can turn on Air conditioning units remotely using a smartphone app, or a doctor can receive bio health information for his patient on his smartphone.

In order to achieve that the following components are required

• Internet connectivity
• A Microchip capable of communicating to internet, preferably using WiFi
• A Microcontroller with memory to run a program for communication
• Some additional hardware to control the device.

There are also Microchips that are Microcontrollers as well as WiFi adapters. Here are some examples.
