Usage

1. Setup:

   • Connect the hardware components as per the circuit schematic.
   • Upload the code to the ESP32 development board.
   • Power on the device.

2. Connecting to WiFi:

   • The device will automatically attempt to connect to the predefined WiFi network.
   • Ensure that the WiFi credentials in the code match your network details.

3. Setting Time Zone:

   • Navigate to the "Set Time Zone" mode using the push buttons.
   • Adjust the time zone by setting the hour and minute offsets.

4. Setting Alarms:

   • Navigate to the alarm settings mode.
   • Set the desired time for each alarm using the push buttons.

5. Monitoring Temperature and Humidity:

   • The device continuously monitors the temperature and humidity.
   • Alerts are displayed on the OLED screen if the temperature or humidity goes beyond predefined thresholds.

6. Alarm Notifications:

   • When an alarm is triggered, the buzzer will sound, and the LED will light up.
   • Press the cancel button to stop the alarm.

This device is a helpful tool for ensuring that medications are taken on time and for monitoring environmental conditions to store medications properly.
