Question

Question #2 (40 pts): Write a Code according to the circuit shown in Figure 1 and the given requirements below. Figure 1. Keypad circuit This code is going to work based on a number guess game.  The first player will enter a four-digit number by using the number pad. All the digits should be different. (It is not needed to be checked in software). The entered digits will be seen on the first line of the LCD screen during the input. After the 4th digit is entered, the number will be saved and “SAVED” should be displayed on the second line of the screen for 2 seconds then the screen will be cleared. (15 pts) Hint: It is recommended to use keypad reading functions that are supplied in the 2nd Laboratory assignment.  The second player will try to guess the number entered by the first player in ten guesses. If the player cannot find the number in ten guesses, the message “YOU LOSE” will be displayed on the first line of the screen and the number entered by the first player will be printed on the second line of the screen for 5 seconds. If the second player finds the number in ten guesses, the message “YOU WIN” will be displayed on the screen for 5 seconds and LED which connected PIN_B0 will be turned on for 5 seconds (20 pts).  After losing or winning ,the loop should start from the beginning (10 pts).  The first guess “Guess1.” will be seen on the first line and second player will enter his/her guess on the first line in continuation of “Guess1.” Then the microcontroller will give a hint to the player according to the entered guess as shown in Figure 2. The hint will be given according to the digits that were guessed correctly and their places. The number of the correct place and correct digit is represented by prefixed “+” sign, the number of the correct digit with incorrect place is represented by prefixed “-“ sign.For example, if the number to be guessed is “1357” and the second player entered a guess as “1325”, the second player found 2 digits on the right place but 1 digit on the wrong place. Then the hint will be shown as “+2-1” after one space from the entered guess as shown in Figure 2 (35 pts).  After the first guess on the second line “Guess2.” will be written and the second player will enter the second guess on the second line as shown in Figure 2 (10 pts). Figure 2. For the first guess  After the second guess, every guess will be entered in the second line and the previous guess and hint will be seen on the first line of the screen as shown in Figure 3 (10 pts). Figure 3. For the other guesses Simulation files and written codes (c files) should be uploaded to the system and sent to the following email addresses. There is no need for any report or screen video.
