You are tasked with designing a Vending Machine system that incorporates a Keypad (4x3) for user input. The keypad has a total of 12 buttons [10 numeric and 2 special character buttons (*,#)] and the 10 numeric buttons represent the following food items of vending machine: 0 Coke 1 Sprite 2 Dew 3 Pepsi 4 Mojo 5 Coffee 6 Drinko 7 Lays 8 Sun 9 Alooz The system has an LCD connected in Port A and 4 LEDs connected in PortB. If anyone comes and presses any key of the keypad then the LCD will show the selected item name. For example if 2 is pressed the LCD will show: "Selected: Dew". Once selected the user can change selection by pressing other options of the keypad as well. Once the user presses '#' the 4 LEDs will start blinking for 2sec with 0.4sec delay and the LCD will show "Thank You" for 2 sec and then it will be cleared. If the user presses **' after selecting an item the display will show "Have A Good Day" and nothing will happen to the LEDs. Now draw the circuit diagram and write the program for ATmega32 based on the above scenario.
