Need help with School Project [4-Digit Door Lock System]
Nov 12, 2024 · Logic Gates (AND, OR, NOT) And the requirements are (Bold text indicate most of our issues): Use four switches for input to simulate the 4-digit PIN entry. The system should have a predefined 4-digit PIN sequence of switch positions that, when correctly set, will unlock the system. The system should have a lock and unlock state.
Logic Gate Vcc and GND purpose? - All About Circuits
Mar 25, 2016 · If you don't have the experience for logic gates, I suggest you to do the real practice, maybe using breadboard to connect the circuit, and using the multi-meter to measure the current for IC and its gates, also measure the voltages for the input and output for the gates, when you have more experience then you can using the logic gates simulation software, only doing …
Connecting logic gates - All About Circuits
Dec 31, 2011 · Logic gates have a parameter called fanout that says how many inputs one output can drive. It may be 3, or 4, or 10 more more, depending on the type of gates you are working with. If you mix logic types, like CMOS, or TTL or LS-TTL, what output can drive what input depends totally on the specific parts.

Oct 29, 2009 · Another way. Tie two equal resistors from each logic input to the non-inverting input of a comparator. Feed the inverting input with a reference voltage which is 3/4 of the High Logic Level. The only time the comparator output will be high is if both logic inputs are High. If either is low, the non-inverting input will be at 1/2 Vh.
