i would suggest you Use ESP32 module , so that you control it wirelessly through WIFI or Bluetooth using a android app.
I am an android and a java developer with 4 years of experience in the IT industry.
I have worked with AndroidX, firebase, GSON,MVVM,RoomDB,Retrofit,
Hope to engage with you on this project.
