 ===== 1. Introduction =====
 The aim of this project is to implement the famous 'Snake' game in an IoT environment. The game is powered by an ESP-WROOM-32S microcontroller, which is connected to an 8x8 RGB matrix used for display and a joystick with which the user can interact to control the movement. The project leverages multiple key concepts and technologies used in the IoT and embedded design worlds, such as system interrupts, driving signals through pins, reading analog values and converting them to digital values, logging data to the flash memory (through SPIFFS), and using Bluetooth to allow the user to interact with the board and perform various actions through sending commands.

+The implementation of the project can be seen in the following pictures and in the attached video on the top of the page.

+The project achieves the proposed objectives: implementing the classic Snake game on a LED matrix and using Bluetooth communication and SPIFFS flash logging to enhance its functionality. The features have been tested and work successfully.
+Improvements can be made, though, especially in the hardware-related zone. For example, there are times where the wires do not make full contact with the RGB matrix on the breadboard, which translates to power cutting off and turning the LEDs off, or having random LEDs turning on. To fix this, the matrix has to be adjusted a little bit, until you see it is working again and it must be ensured the matrix stays in a fixed position in order to reduce any possibility of this occuring.
+Another improvement is regarding the code size, which consumes close to 90% of the available code memory. This is because the project includes multiple libraries (Bluetooth, SPIFFS, AdaFruit_NeoPixel, etc)  that take high amounts of space.
