Question

Create a logic circuit using a keypad with 10 digits 0-9

The circuit should go to output red/green lightbulb to see whether the two-digit password entered on the keypad is correct.

Answer 1

To create a logic circuit using a keypad with 10 digits 0-9 to check if a two-digit password is correct, you can use a combination of logic gates and a red/green lightbulb.

Step-by-step explanation:

To create a logic circuit using a keypad with 10 digits 0-9 to check if a two-digit password is correct, you can use a combination of logic gates and a red/green lightbulb. Here's one way to set up the circuit:

1. Connect each digit of the keypad to an input of the logic gates.
2. Use the logic gates to compare the entered password with the correct password.
3. If the passwords match, the output of the logic gates will activate the green lightbulb, indicating a correct password. Otherwise, the red lightbulb will be activated.

This circuit can be implemented using digital logic components, such as AND, OR, and NOT gates, as well as flip-flops and decoders. The specific implementation will depend on the exact requirements of the system and the available components.
