Arduino Guest for Team City (no need plugins for teamcity. only guest rights) It's used for read information about current builds (FIAILED,RUNNING, SUCCESS) And display build states via light traffic For connection to network are used ESP8266 wifi module For execute programm are used Arduino Leonardo

RED - at least one build is failed RED+YELLOW - failed build is running GREEN - all builds are ok

BLINKING YELLOW - team city unavailable BLINKING RED - team city not founded BLINKING YELLOW - RED - wifi error

Programm contains algoritm for parsing on fly big data (more than RAM in arduino) from team city

Algorithm read ids of configurations then read state for every id (ids are stored in EEPROM, because ids data can be mre than RAM in arduino)
