1. Install the Bluetooth module on the Arduino board and run this app on the mobile phone to establish Bluetooth communication between the mobile phone and Arduino.
2. Connect the temperature control heater and temperature/humidity sensor to the Arduino and have it automatically adjust to the temperature set in the mobile phone.
3. Connect the light to the Arduino and turn the light on and off at the set time on the day of the week set on the mobile phone.
4. Connect RTC (RealTimeClock) to Arduino and ensure that it is calibrated to the date and time set in the mobile phone.
5. The communication command format for control between a mobile phone and Arduino is as follows. (Data transmitted to Arduino when each button is pressed)
1) Current date "datxxyyzz." xx=Year-2000, yy=Month+1, zz=Day
2) Current time “timxxyyzz.” xx=hours, yy=minutes, zz=seconds
3) Timer on/off time "beginwwxxendyyzznnnnnnn."
ww start, xx start minutes, yy end, zz end minutes, nnnnnnn Sunday to Saturday 0 on, 1 off
4) Lighting automatic mode “la.”
5) Lighting manual mode “lm.”
6) Heater automatic mode “ha.”
7) Heater manual mode “hm.”
8) Set temperature “temxx.” xx=temperature
9) Lights on "lon."
10) Light off "loff."
11) Heater on "hon."
12) Heater off “hoff.”
* The . added at the end is treated as the end of transmission in the Arduino program.
