Smart Esp32 KeyChain with 5x5 RGB Led Matrix
The project is not ready yet, I have only finished the schematics.
Main idea: A smart keychain capable of displaying emotions on a 5x5 grid and turning on automatically thanks to the GY 521 sensor. We have also integrated a touch button for automatic Bluetooth activation, and in the future we will add a mini speaker to the next design.
