Access your microcontroller from anywhere in the world (Part 1) Microcontrollers are an amazingly cheap way to automate and control the world around you, but in a world where a Wi-Fi connection is available almost anywhere it has not always been as proportionally cheap to get your microcontroller project connected to the outside world. That…
Access your microcontroller from anywhere in the world (Part 3) Basic server example In this example we are going to configure the module as an access point so that Wi-Fi clients such as PCs, tablets, or smartphones can directly connect to it. We can then serve a very basic web page to the connected client….
Access your microcontroller from anywhere in the world (Part 2) Requesting a web page over a TCP connection Now we are connected to the world, let’s try requesting a web page from a website on the internet (Google). First we need to connect to the server that will be serving the page we require using…
One of the most common uses for microcontrollers is for interfacing to various sensors to monitor the world around you. With an Arduino board you can read the value from a temperature sensor and output it to a computer in a matter of minutes. But what if your Arduino and sensor needs to be remotely…
