A display cabinet that can change the theme that you want. When you go nearby the LEDs will turn on with different colour and pattern.
This cabinet is 30cm in height, length and width.
There are pcb in the bottom, sensor at the front and a hole behind that allow main power supply to come in.
The 2 semi-circle at the front and back allow me to open. The front is for me to change the display and the back allow me to change different theme.
I have one ultra sonic sensor in fornt when people walk nearby, the sensor will active the light and the lights will on.
