64. Sleep Mode with Button Press Wake-Up

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

• Arduino will be in sleep mode to conserve power.
• When a push button connected to the Arduino UNO is pressed:
  1. Wake up from sleep mode.
  2. Read the ADC value of a potentiometer connected to the Arduino UNO.
  3. Print the ADC value on the Serial Monitor.
  4. Return back to sleep mode.
• The system repeats the process each time the button is pressed.
