As the user moves closer to the frame, a bigger circle is added to it.
The frame has a neon glowing surface which has a memory for light, meaning the user will be able to see a glow of the circle on the display as it gets bigger.
LEDs are integrated on a rectangular part which is connected to a Servo motor. This motor rotates and with it the LEDs rotate also.
An Ultrasonic sensor is used to sense the user and to detect the distance of the user and the frame.
All the electronic parts are connected to a Arduino Uno board.
