So transistors react faster than AND gates on this case? I’m just asking because I made something similar with a standard seven-segment display and used an AND gate for the 9 reset. Mine did display A for a second before it went back to zero, but the transistor here reacts instantly. It’s so fast you can’t even see the reset wire blink red!

Just remember current limiting resistors are required when making actual circuits

Yes, and its because in reality the and gates placed in ICs and transistors are much smaller, thats why i used the transistor
