  1. The Arduino UNO microcontroller reads temperature data from the NTC 103 Thermistor and displays it on the LCD Display.
  2. Based on the temperature readings, the microcontroller controls the operation of the Peltier module.
  3. The Peltier module acts as a thermoelectric cooler, transferring heat from the inside of the refrigerator to the outside, thereby cooling the interior.
  4. The cooling fan with heat sink helps dissipate heat generated by the Peltier module, maintaining efficient cooling.
  5. The relay module is used to control the power supply to the Peltier module, allowing the microcontroller to turn it on or off as needed.
  6. The potentiometer allows users to manually adjust the set temperature of the refrigerator, providing flexibility in temperature control.
  7. The 18650 Li-ion batteries provide backup power in case of a power outage, ensuring continuous operation and temperature regulation.
