matrix mini clock with alarm, thermometer and hygrometer (2)

original article
   Because I use DHT22 (AM2302 sensor) am change the sketck (mini_clock_1_3_b.ino)  to see temperature with number after decimal point, like in next photo
- negative tmperature > -10 degree Celsius:
- negative temperature more than -10 degree Celsius
- positive temperature less than 10 degree Celsius
- positive temperature more than 10 degree Celsius
