Once I understood how to properly use this library and had successful attempts, I moved on to develop a more complex mechanism. Inspired by the previously mentioned Twitch Plays Pokémon, I devised a device which would collect tweets with any one of the directional words "up", "down", "left" and "right" (excluding retweets, in order to prevent duplicates) and use them as commands for the microcontroller. The interesting thing about these words is that they are extensively used in the English language with other conotations, which makes the search especially random. | Once I understood how to properly use this library and had successful attempts, I moved on to develop a more complex mechanism.
