As mentioned, the project worked by creating a grid with four UWB(Ultrawide Band) chips placed in the corner of the room and sending signals to the handheld chip. The handheld chip will send the location data to the Arduino Nano according to its position in the grid. The motor and the eye in the P5 controlled by the Arduino Nano will move according to the received location data. Here is a diagram of how the UWB locator, Arduino Nano board, the 'phone'(hand-held UWB receiver), and the P5 screen communicate with each other when the user is holding the 'phone' and walks around the room.
