LED Board with 8 RGB 5050 LEDs for level indication
Product information:
With this board you can, for example, easily indicate the water level in a tank with 8 LEDs.
Connect 5VDC to the VCC connector. Then connect GND to one of the RGB pins (or a combination of pins to mix a color).
The LEDs will then light up as soon as current flows from the D0 to D7 pins to ground (for example through a liquid or by touch).
All LEDs get the same color.
