you will design and implement a ESP IDF-based IoT system that uses Amazon Alexa voice control to either lock or unlock the "set time" functionality of a ESP32-based embedded system that has a keypad, buzzer, and LCD interface and behaves as follows:

1) It always displays the current time in HH:MM:SS am/pm format:

2) If the "set time" functionality is UNLOCKED (by an Alexa voice command), then the time can be set from the keypad as follows:

a. The '*' (asterick) key initiates "set time" mode

b. In "set mode", the new time can by entered directly using 4 digits followed by the '#' key

3) If the keypad functionality is LOCKED (by the an Alexa voice command), then setting the time is not allowed until it is UNLOCKED again

4) The "set time" functionality can be UNLOCKED in one of the following ways:

a. Entering a 3 digit passcode followed by the '#' key

b. An Alexa voice command

5) A one-second beep sound is used to indicate when the system is UNLOCKED in either of the two ways. * You are required to use
