Can you guess my password? :D
Operating Instructions Below!
- The switches represent a decimal numerical keypad in this order:
1 2 3
4 5 6
7 8 9
0
The last switch to the right of the 0 switch is the circuit clock (CLK) signal.
Instructions:
How to enter a number:
1) Select a logical switch from the numeric keypad and enable it to 1 (HIGH).
2) Select the clock (CLK) switch and set it to 0 (LOW), wait for the number to appear on the displays.
3) Select the CLK switch again to disable it with value 1 (HIGH) and the selected keypad switch to 0 (LOW).
When the correct 4-digit number is entered, the red LED will switch off and the green LED will switch on!
Congratulations :D
4) Profit?????
Notes:
- Zoom in so that all four 7SDs are in view along with the logical switches in the bottom left corner for easier switching.
- The top right side of the simulation contains a shift register, bottom right contains a DEC to BCD converter, and the bottom middle contains the correct password logic.
