Estragon and Vladimir's absurd dialogues in Sam Beckett's play Waiting For Godot are literary history. These two Arduinos remix these dialogues in an endless loop.
The two "protagonists" are triggered by a sound sensor. Every time a sound from the environment is received, the Arduino, who is in turn speaking, begins with a randomly selected sentence from the text of Waiting For Godot.
Technically, the two Arduino communicate with the help of the Wire Library.
The dialogues in the Sam Beckett's original are already absurd, but the communication between the Arduinos is really fascinating. It sometimes makes sense in a bizarre way and often is just fun.
Take a minute or two and listen to them! :)
