* DEFINITION
* This a set of math functions that deal with time. The functions accept
* 4-digit time values and 4-digit time of day values. Time values are
* interpreted as hours-minutes and are valid if all digits are numeric and
* 9 or less, except the second-to-last digit must be 5 or less. Time of day
* values are valid if they conform to normally accepted clock values of
* 1:00 to 12:59 for a 12-hour clock or 00:00 to 23:59 for a 24-hour clock.
* DEFINITION
* This is the header file for a library module used to calculate the median
* of a list of values. It finds the value that would be in the center if
* the list were sorted. If the list contains an even number of values, the
* lower of the two center values is reported. The values themselves are not
* sorted or modified in any way. This algorithm can be used as a filtering
* tool for rejecting noisy data.
The LM158 series consists of two independent, high gain,
internally frequency compensated operational amplifiers
which were designed specifically to operate from a single
power supply over a wide range of voltages. Operation from
split power supplies is also possible and the low power
supply current drain is independent of the magnitude of the
power supply voltage.

Digital Thermostat
We build a digital thermostat for home applications, which controls the room temperature. I
used the AT90S2313 microprocessor of ATMEL. The digital thermostat opens the main heating valve of
the apartment and the hot water flows in the radiators.
