1.8 tri-color (red, green and blue) full-color LEDs , scanning is the control method
2.Same as the digital tube control mode, the bit selection control corresponds to the 
3.LED lighting, and the segment selection control color
Different color changes can be produced by different programs
Wiring method
The 8 pins D0~D7 control these 8 LEDs respectively,so as long as they are connected to the digital pins corresponding to arduino(our experiment only needs to connect to 2~9 pins in turn).In addition,there are three RGB feet next to it,which need to be connected to GND,bright red when connected to R,bright green when connected to G,bright blue when connected to B,and all three are bright when connected at the same time

Package Type:
All goods will pack into cartons and wrapped full of waterproof tape before shippment .
