Real time clock function: Tone after a preset time, when there is a power outage and resumes, it automatically reset the time.
-
Temperature display function: Under the time display mode, press PLUS, can display the current temperature.
-
Many mode display function: Outer LED display has four modes, can cooperate to add key implementation, through the model key.
- Mode 0: This is the default display mode, all the 1-12 hours red digital tube light, when the clock through a second, is the green digital tube will take turns to light up.
- Mode 1: As the clock goes through a second, outer ring LED lits consecutively, that is after 60 seconds all the LEDs on the outer ring displays. The next minute, all leds light up, and through the clock for a second repeats the same. This goes alternatively.
- Mode 2: when the clock goes through a second, outer ring take turns to light up a LED. The first second, first LED lights, 2 second only the second LED lights.
- Mode 3: when the clock goes through a second, outer LED turns off. The first second, only the first LED out, then only the second LED out for 2 seconds.
Key Functions:
PLUS key, for years, months, days, hours, minutes, seconds add operation. According to the numerical sum 1 at a time MODE key, can be in display clock, switch to the year, month, day, hours, minutes, alarm clock, the adjustment of outer ring LED display state. To use add key to the year, month, day, hours, minutes, seconds, and display mode to adjust RST key, press the reset button, then the MCU reset.
