First practical works, dot-matrix large-screen speech induction meter--works show

Single-chip computer played for several years, a variety of modules also bought a lot, but did not make any decent knock. Reflection, decided to start from a simple and practical, make a timepiece, convenient to grasp the time.

Main Features:

1. Using 3 chip MAX7219 lattice module, make up 8*24 dot matrix screen, dynamic display date or time;

2. Human body induction, when someone lit the dot-matrix screen, after time-out system into the drop point mode, reduce power consumption, so that battery power becomes possible;

3. Use voice Broadcast module SC5B10 to realize the hourly timekeeping;

4. Does not set the key, through the serial port control, in the future may install the Bluetooth or other wireless according to the need, (the necessary operation is mainly right, but the time is very accurate, after the first set up does not need the manual intervention)

5. Battery-powered and wireless charging for easy movement.

When sensing the activity, enable the display, display 4 seconds, and then display the 2 second date, and then back to the time mode, so repeatedly, when the detection of less than 30 seconds of personnel activity into the power-off state, closed display, but still able to time the hour.
