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

    2. also you must add file form https://github.com/tehniq3/max7219_matrix_clock/blob/master/FontLEDClock1.h in subdirectory when you have the sketch...

  2. Here I am talking about the same subject: If in this clock project, if you replaced the buttons with an IR Remote Control (NEC protocol maybe), that would be a charm, even for the ease of controlling the clock remotely.
    I don't do it because I don't have enough knowledge yet! Thank
