Binary coded, finger sensitive (finger amplifier not included) security system consisting of 10 bits. Uses a shift register and logic, LED's are just for simulation. Input a logical value of 1(High) by using the bottom NO push button, and a value of 0(Low), by pressing the top button. The shift register will display the code while your entering it, and if correct, the LED at the output will illuminate on the 10th digit. Improvements could include, but of course, are not limited to: a timer (to limit how often you can guess and re-guess), and (a counter that will limit how many times you can enter the code within a certain time period). NOTE: because of the propigational gate delay, you may have to hold down the push buttons for about 1-3 seconds.
