Dear Friend., This is the first time I am seeing a valuable video. All other videos are filled with horrible background music that will destroy our ear drums.Good Luck. I will watch all your videos peacefully. Please do not add any background music like others do. Instead your commentry is valuable and worth.

Is it possible to use 74LS374 instead of 74LS373?

Hi thank you for this video, it works and is great!!!
I want to run longer cables from the control board to the switches... the moment it's longer than about a meter, the system malfunctions and the buzzer sounds non-stop. Is it because of too much resistance in the long cables? What do you suggest i do if i want long cables (20 meters)?
