Sample Code of http://ohurochan.jp/blog/?p=446 Added SerialController to control BitPattern from PC via Serial. Based on https://developer.mbed.org/users/tandk1124/code/LED_BitPattern/
Fork of
LED_BitPattern
by 
Takuma Arai
Added Control class for SeirialPC. You can change LED Lighting Bit Pattern from PC Serial. Type "1" to set countup. Type "0" to set countdown.
