Similar projects worth following
The pcb cube is a fun little gadget for testing pcb capacitive sensor for future projects.

There are 4 sides with red,yellow,blue,green leds and 2 sides with LDRs as switch sensor

It's programmed with 3 modes. 

Touch both LRDs and mode 1 starts

Mode 1: touch a side pannel and a led turns on release the pannel led turns off 

Touch the top side and the blue led side = start mode 2

Mode 2: touch a side pannel and led stays on till all sides are touched , mode 3 starts

Mode 3: a random side led turns on. Press this side and the led goes off, randomly and other turns on.

Looks cool. But what does it do?

It won't do anything when it's turned off and not connected to any usb power cabled that's plugged in a charger on the power grid.

A beauty it is, thanks!
