Home clock with 3 temperature sensors

2005, customer: private project, 1 developer
result: the sample works 6 years – time may be set only at midnight :) due to leak of MC memory
dev. OS: Windows XP; MC: ATtiny26; languages: C; tools: PN, AVR C cross-compiler

50x50x25mm clock that shows time and 3 temperatures at 4 digits LED screen in sliding mode (corresponding value is shifted from 1 of 4 sides each 2,5 seconds). It has auto brightness with 16 levels controlled by light sensor. RGB color panel to show outside temperature with color was designed but was not realized in the code. Power unit is external.
Watch its movie ThermoHome-Vid01.
