BASYS 3 Board Project #2 Electronic Lock

CSE 490/590

BASYS 3 Board Project #2
Electronic Lock
Design an electronic combination lock. A four digit code can be entered by using the
pushbuttons and slider switches as in Project #1. After the number has been entered, the user
should press momentary push button C (center) to indicate that the code entering is complete.
When the correct combination is entered and the device unlocks, the LEDs will flash. If two
attempts are made to unlock the device without correctly entering the combination, the device
should be deactivated for 10 seconds. The seven segment display will be used to display the
state of the lock. The states are: LOC (locked), UnLC (unlocked), and PAUS (deactivated).
When the device is unlocked, it can be locked by pressing momentary push button L (left). The
entire code must be entered within 30 seconds (from the first button press to the last button
press). The combination for your lock should be the number of digits in your username,
followed by 5 if you are in CSE 590 or 4 if you are in CSE 490, followed by the sum of the first
two digits. For example, if your username is csestaff and you are in CSE 490, your combination
would be 8412.
Guessing Game
Design a two player guessing game. The game starts with the four digit seven segment display
illuminated with “PL 1” indicating that player #1 should enter a number between 0x0000 and
0xFFFF. The number is entered using the procedure outlined in Project #1. After the number
has been entered, player #1 should press momentary push button D (down). The seven segment
displays are used to indicate this by displaying “PL 2”. It is now player #2’s turn. Player #2
repeatedly enters four digit numbers until he or she correctly guesses the number entered by
player #1. The procedure for entering the four digit number is the same as it was for player #1.
When an incorrect number is entered, the display should indicate if the guess was too high (“2
HI”) or too low (“2 LO”). When the correct guess is entered the LEDs should blink in
celebration, and the number of guesses required should be displayed on the seven segment
display.
Calculator
Design a calculator. The first operand is entered using the procedure outlined in Project #1.
After the first operand is entered, the second operand can be entered. After the second operand
has been entered, the user can select the operator by pressing momentary push button L (left) for
addition, R (right) for subtraction, or D (down) for logically left shift operand 1 by the count
represented by operand 2. If the user would like to enter another set of numbers, momentary
push button U (up) should be pressed to clear the display (all zeros) and start over.
