The ESP32-Tyranitar project is centered around the widely-used and budget-friendly microcontroller, ESP32, aiming to breathe life into one of Generation 2's iconic Pokémon, Tyranitar. Upon activation through a simple tap on the model, Tyranitar unleashes its distinctive cry sound, accompanied by a dynamic display of intense flickering lights, showcasing the characteristic of this pokemon based on it's description.
The code is written in micropython.
