Description:
SoftCollection LED Line program lets you make a virtual LED table in the air.
You can make simple hardware, as shown in the picture below, that consists of an 8 LEDs line,
9 resistors of 470 Ohm each, a button and a pendulum that presses this button.
If you will move LED line left and right 5-10 times per second and desired LEDs will shine at
desired moments, you will see words in the air.
