65. Sleep Mode with Periodic Wake-Up

Design a power-efficient system using the Arduino UNO with the following functionality:

  • Arduino will be in sleep mode to reduce power consumption.
  • After every 1 minute:
    1. Read the ADC value from a potentiometer.
    2. Prints the ADC value on the Serial Monitor.
    3. Returns to sleep mode after completing the task.
  • The system repeats the process after every 1 minute.

NOTE: To wake up the Arduino from sleep mode, multiple approaches can be used. However, choose a method that is most power-efficient and provides high time accuracy.
