LED CUBE TEAM
Blue LED matrix (8x16) program. Gets text string through bluetooth and displays it on led matrix. Also has a clock function- get system time from a phone through bluetooth and enters clock mode. In clock mode it acts as a clock showing hours and minutes and blinking led every second. Clock mode can be broken if a text string is received through bluetooth.
