Program to count seconds, as best I can without a clock such as a DS3231. Each loop, the program runs delay(993), which is close to having a 1 second loop, with logic and displaying the counter to the LCD. The accuracy various widely. Only good when approx time is okay. Bar graph...
This is the DS3231 Precision RTC FeatherWing: it adds an extremely accurate I2C-integrated Real Time Clock (RTC) with a Temperature Compensated Crystal Oscillator (TCXO) to any Feather main board. This RTC is the most precise you can get in a small, low power package. Using our Feather ...
I am using Windows OS, the Arduino board is connected over USB to the PC. How can I communicate in Arduino Control Center with a connected Arduino board? Does the Arduino board need to be connected to the PC and Arduino Control Center always? Will it continue to work if the PC failed ...

RTC DS3231 [Buyhere] [Datasheet] 3V CR3032 battery (for DS3231) In addition, you’ll need an Arduino of any kind (preferably a Nano to minimize the size of the project), a breadboard, jumper wires as well as the Arduino IDE installed on your PC. ...
Digital pin-3,4 acts as alarm pin from the first arduino, The A3 pin on the 2nd arduino reads this status to process inside the 2nd arduino. TFT ILI9163 is connected on the 2nd arduino to display time, alarm time etc. The RTC DS3231 is shared by both these arduinos. The relay conn...

outdoor unit can be powered with batteries and the indoor unit with an AC adapter. The outdoor unit measures the temperature and the humidity and sends the values to the main indoor unit. Here these values are printed on the LCD along with the data and time values from the DS3231 RTC ...
SCL: It is a serial clock pin for communication through I2C interface. Vcc: Apply 3.3V-5V at this pin. DVI: This is the sensor’s pin. It is not present on the breakout board. If you want to set power-down mode, apply Vcc at this pin. ...
