This project was created as an attempt to use Twitter [https://en.wikipedia.org/wiki/Application_programming_interface API] to send commands to a microcontroller. Its basic structure consists of a matrix of LEDs in which only one of them is lit up at a time. The Twitter API is used to collect information from tweets in order to choose which LED to light up. | This project was created as an attempt to use Twitter [https://en.wikipedia.org/wiki/Application_programming_interface API] to send commands to a microcontroller.

At first, the idea was to collect and analyze information from tweets all around the world, so as to generate inputs. However, as this was my first time working with both microcontrollers and APIs, it was preferred to lower the complexity of this interaction to the level of generating inputs from individual tweets using the search feature. | At first, the idea was to collect and analyze information from tweets all around the world, so as to generate inputs.

The core of this project is the use of ESP8266 in order to connect to the internet and access the Twitter API. It is worth mentioning, though, that I was required to apply for a developer Twitter account in order to access the API. | The core of this project is the use of ESP8266 in order to connect to the internet and access the Twitter API.

In order to develop this project, most of my research was focused on tweet-to-microcontroller interactions on platforms such as Pinterest, Instructables and Hackaday. The two examples below are, respectively, [https://www.instructables.com/id/Mood-Lamp-Based-on-Twitter-Hashtags/ Mood Lamp Based on Twitter Hashtags] and [https://www.instructables.com/id/Twitter-Controlled-Pet-Feeder/ Twitter-Controlled Pet Feeder]. | In order to develop this project, most of my research was focused on tweet-to-microcontroller interactions on platforms such as Pinterest, Instructables and Hackaday.
