Basically a button downstairs wirelessly flashes "COME DOWNSTAIRS" on an LCD in my room , so I know someone wants me even with headphones on and my door closed.
update 8/4/26: updated it more heres whats up: had to add more code to project to add another button, also design a 3d printed case for the sender parts and reciever parts to hide wires to to make it look more aesthestic!!
