UPDATE 26/04/2020 - WORKS! [ youtu.be/QTnMmF8D918 ]
This circuit simulates an electronic keypad, similar to that for unlocking electronic locks.. a code is required. Unfortunately I don't have the code, and I can't even get it from the KIT seller. I found 7531 online but it doesn't work.. Am I wrong in your opinion?
We understand that the code is OK when once accepted by the circuit, the LED on the right turn ON
I hope some of you can help me to find a solution :)
