Description:  This is a DIY kit, need to assemble it yourself, if you need to buy finished one.  Type: IV-11.  RGB full-color background lamp.  Using a 5VDC power supply.    Function:  1. The use of high precision clock chip display time (upgrade: support 12/24 hours display);  2. The use of high precision clock chip display date (Upgrade: Support year, month, day/month, day, year/day, month, year format);  3. Automatic switch setting;  4. With a timing alarm clock that can be switched off and adjusted;  5. Using interrupt mode to read the DS18B20 temperature code, read the temperature value is accurate, does not beat. Unlike regular reading of the DS18B20 code, the code handles things a little more and is not normal;  6. Can be switched automatically alternately display time, date, temperature (Duration can be set);  7. Two breathing lamps in the center, the color can be adjusted by remote control;  8. Under the electronic tube withRGBled, the effect can be closed. Display mode controllable (Breath 5 times, Automatic color switching).  IV11 fluorescent tube clock infrared remote control button protocol:  Button marking: Function;  Power button: Turn on/off the automatic switch function;  Back button:  Display time mode: 12/24 hour switching;  Display date mode: Year Month Day/Day Month Year/Month Day Mode Switch;  Display temperature mode: Celsius °C / Fahrenheit F mode switching;  Time switch mode: 3 kinds time period switching;  Switching time mode: Turn automatic display on/off;  - button: In adjustable mode (when the tube value is flashing), the value is reduced;  + button: In adjustable mode (when the tube value is flashing), the value is increased;  C button: In the automatic on/off mode, the modification time is confirmed (It can't modify when the format does not match);  Rewind button: The rgbLED under the tube is in the breathing state, the last color;  Fast forward button: The rgbLED under the tube is in the breathing state, the next color;  Pause button:  Alarm mode: Turn the alarm on/off;  Timing turn on/off  mode: Start/end time period switching;  Except the above two modes: The last LED (week) is turned off/on;  TEST button: In adjustable mode (such as time mode), adjust the position to switch back and forth;  MENU button: On/off (automatic switching color of rgbLED under the tube);  1: Time mode;  2: Date mode;  3: Alarm setting mode;  4: Temperature mode;  5: Test mode;  6: Auto power on/off setting mode;  7: Time, date, temperature switching time setting, whether to start automatic switching setting;  8: The 6 LEDs under the tube are turned off/blinking/constantly lit, and the three states are switched back and forth.  9: Color switching of 2 breathing rgbLEDs in the middle of the tube:  10：2 breath rgbLED in the middle of the tube is turned off/on.  IV11 Fluorescent Tube Clock List: 6cm*20cm Circuit board*1;   DS3231 DIP clock chip: U4*1;  6803 SMD chip: U9*1;  1117-3.3 SMD chip: U13*1;  5.5*2.
